     As used in the present description, the term “salt” of aspartic acid indicates any salt comprising a metal salt and an amine salt and the like, provided that the antioxidant effect of aspartic acid is not impaired. The metal salt may comprise an alkaline metal salt, an alkaline earth metal salt and the like. The amine salt may comprise a triethylamine salt, a benzylamine salt and the like. 
     As used in the present description, the term “derivatives” of aspartic acid indicates an aspartic acid molecule that is covalently bound to any atomic group via its amino group, carboxyl group, or side chain, provided that the antioxidant effect of aspartic acid is not impaired. The atomic group comprises, but is not limited to, a protective group, such as N-phenylacetyl group, and 4,4′-dimethoxytrityl (DMT) group, a biopolymer, such as a protein, a peptide, a saccharide, a lipid, and a nucleic acid; a synthetic polymer, such as a polystyrene, a polyethylene, a polyvinyl, and a polyester; and a functional group such as an ester group. The ester group may comprise, for example, an aliphatic ester, such as methyl ester, and ethyl ester, and an aromatic ester. 
     An amino acid has optical isomers which are the L-form and D-form. A natural protein has L-amino acids bound by peptide bonds and only L-amino acids are employed excluding some exceptions such as a bacterial cell wall. Therefore, it has been considered that in a mammal including a human only L-amino acids are present and only L-amino acids are utilized (Kinouchi, T. et al., TANPAKUSHITSU KAKUSAN KOSO (PROTEIN, NUCLEIC ACID AND ENZYME), 50:453-460 (2005), Lehninger Principles of Biochemistry [Vol. 1] 2nd ed., pp 132-147 (1993), Japanese-language translation, Hirokawa Shoten Ltd., Harper&#39;s Biochemistry, Original version, 22nd ed., pp 21-30 (1991), Japanese-language translation Maruzen Co., Ltd.). Accordingly, only L-amino acids have been mostly employed as amino acids academically and industrially for a long time. 
     Exceptional cases where a D-amino acid is employed are, for example, a case of using as a raw material for an antibiotics produced by a microorganism, and, a case of a food additive employing a D-amino acid in a DL-amino acid mixture for the purpose of reducing cost of fractionating only an L-amino acid from a mixture of the L- and D-amino acids, which are obtained in equimolar amounts by synthesizing the amino acids. Nevertheless, there has been no case of using only D-amino acid industrially as a bioactive substance. 
     D-aspartic acid is found to be localized in the testis or the pineal body, and it is known to be involved in the control of hormone secretion (Japanese Patent Unexamined Publication No. 2005-3558). However, physiological activity of D-aspartic acid in the skin has not been clearly elucidated. 
     As shown in the following Examples, it has not been known that L- and D-aspartic acids can suppress oxidative damages so far. Thus, the antioxidant composition comprising L- and/or D-aspartic acid according to the present invention is a novel invention. 
     Recently, it was reported that ddY mice were allowed to ingest freely a 10 mM aqueous solution of a D-amino acid for two weeks and then examined for the D-amino acid concentration in each organ, which was 3 to 1000 pmol per gland in the pineal body and 2 to 500 nmol per wet gram in the brain tissue (Morikawa, A. et al., Amino Acids, 32:13-20 (2007)). Based on this, the lower limit for daily intake amount of L- and D-aspartic acids that are contained in the composition of the present invention is calculated as described below. 
     The aspartic acid of the present invention has an effect on suppressing oxidative damages in cultured human fibroblast cells at the concentrations of 0.1 μM (micro-molar) to 10 μM (micro-molar), as shown in the following examples. Thus, the amount of the aspartic acid that is contained in the agent for improving skin conditions, an external preparation for skin, and a food composition of the present invention may be any content, provided that the aspartic acid in the above concentration range is distributed to fibroblast cells in a skin tissue of a living organism. When the composition of the present invention is an external preparation, the content of the aspartic acid may be 0.000015% by weight to 50% by weight, or up to the maximum weight concentration that can be formulated, in the total composition of the present invention. Specifically, when the composition is an external preparation, the content of the aspartic acid is preferably 0.00003% by weight to 30% by weight, and the most preferably 0.0003% by weight to 3% by weight. When the composition of the present invention is an internal agent, the content of the aspartic acid may be 0.00001% by weight to 100% by weight. When the composition of the present invention is an internal agent, the content of the aspartic acid is preferably 0.00002% by weight to 80% by weight and the most preferably 0.0002% by weight to 60% by weight. Further, the lower limit of a daily intake amount of D-aspartic acid that is contained in the composition of the present invention may be 0.01 ng, preferably 0.1 ng, and more preferably 1 ng per 1 kg of body weight. The lower limit of a daily intake amount of L-aspartic acid that is contained in the composition of the present invention is an amount that is less than the general dose of commercially available medicines (20 mg per 1 kg of body weight), e.g., 0.01 mg, preferably 0.1 mg, and more preferably 1 mg per 1 kg of body weight. 
     The composition of the present invention may further comprise, in addition to the single body of aspartic acid, a salt of aspartic acid and/or a derivative capable of releasing aspartic acid by a drug metabolizing enzyme and the like in vivo, one or more pharmaceutically acceptable additives, provided that the antioxidative effect of aspartic acid on oxidative damages is not impaired. Such an additive comprises, but is not limited to, a diluent and an extender, a binder and an adhesive, a lubricant, a glidant, a plasticizer, a disintegrant, a carrier solvent, a buffering agent, a colorant, a flavoring agent, a sweetener, a preservative and a stabilizer, an adsorbent, as well as other pharmaceutical additives known to those skilled in the art. 
     The composition of the present invention may be prepared by only using, as an active ingredient, aspartic acid, salts of aspartic acid and/or derivatives capable of releasing aspartic acid by a drug metabolizing enzyme and the like in vivo. However, within the range that the effect on oxidative damages of the present invention is not impaired, it may be appropriately formulated with other components that are used for an external preparation for the skin like cosmetics including quasi drugs and pharmaceutical products, if necessary. Examples of other ingredients (i.e., optionally formulated ingredients) comprise an oil, a surface active agent, a powder, a colorant, water, alcohols, a thickening agent, a chelating agent, silicones, an antioxidant, an UV absorbing agent, a moisturizing agent, a flavoring agent, various pharmaceutically active ingredients, a preservative, a pH adjusting agent, and a neutralizing agent. 
     A dosage form of an antioxidant composition of the present invention that is used for suppressing and/or improving skin conditions (herein below, referred to as an “agent for improving skin conditions”) may be any one that is commonly used for a quasi drug composition and a pharmaceutical composition comprising an external preparation for skin like an ointment, a cream, an emulsion, a lotion, a pack, gel, and a patch; and an oral preparation like a powder, granules, a soft capsule, and a tablet; a nasal preparation like a nasal spray; and an injection solution. 
     A dosage form of the external preparation for the skin according to the present invention is not specifically limited, provided that it is conventionally used for an external preparation for the skin, and it comprises an ointment, a cream, an emulsion, a lotion, a pack, a gel, and a patch. 
     The food composition of the present invention may further comprise, in addition to aspartic acid, salts of aspartic acid and/or derivatives capable of releasing aspartic acid by a drug metabolizing enzyme and the like in vivo, a flavoring agent, a colorant, a preservative, and other components that can be used for a food product, provided that the effect of aspartic acid on oxidative damages is not impaired. 
     The food composition of the present invention may be any one employed conventionally as a food composition comprising, but not limited to, a candy, a cookie, bean paste, a French dressing, a mayonnaise, a French bread, a soy sauce, yogurt, dried seasoning powder for rice, seasoning sauce/sauce for natto (Japanese fermented soybean), natto, unrefined black vinegar. 
     ROS are known to cause not only skin disorders but also cataract. They are believed not only to disturb lipid constitution by producing lipid peroxides to polyunsaturated fatty acids inside crystalline lens via reduction of hydrogen peroxide and free radical chain reactions, but also to impair the membrane function by denaturing proteins eventually causing opacity of the lens.

According to the findings above and the Examples described below, D- and/or L-aspartic acid having an antioxidant activity is effective for prophylaxis or treatment of cataract.

     DESCRIPTION OF EMBODIMENTS 
     Examples of the present invention described below are intended only to exemplify the present invention rather than to limit the technical scope thereof. The technical scope of the present invention is limited only by the description in claims. 
     Example 1 
     Experiment for Evaluation of Antioxidant Effect 
     1. Object 
     ROS include reactive oxygen species in the narrow sense comprising superoxide anion, hydroxyl radical, hydroperoxide and singlet oxygen, and reactive oxygen species in the broad sense comprising an alkoxy radical, hydroperoxyl radical, a peroxyl radical, hydroperoxide, and a transition metal-oxygen complex and the like. Among the ROS, hydroxyl radical has the most potent oxidizing activity, but has very short lifetime. As such, it oxidizes non-selectively body components like nucleic acids, proteins, and lipids that are present in the vicinity of their generation site. However, peroxyl radical has a weak oxidizing activity but is relatively stable. As such, it can diffuse and cause a cell membrane damage via free radical chain reactions of polyunsaturated fatty acids. Meanwhile, hydroxyl radical generates a peroxyl radical but no hydroxyl radical is generated from a peroxyl radical. Since the working mechanism is different between a hydroxyl radical and a peroxyl radical, an effective antioxidant may be also different for each of them. For such reasons, in the present examples, an antioxidant effect was evaluated for both hydrogen peroxide and 2,2′-azobis (2-amidinopropane) dihydrochloride salt (herein below, referred to as “AAPH”), that are the representative examples of a compound which can generate hydroxyl radical and a peroxyl radical, respectively. As a positive control, carnosine having a known antioxidant activity was used. 
     2. Materials and Methods 
     2-1. Cells 
     For the evaluation of an antioxidant effect on hydrogen peroxide, human neonatal skin fibroblast cells (trade name: Cryo NHDF-Neo, manufactured by Sankyo Junyaku Co., Ltd.) were inoculated to a 24-well plate to have 1×10 5  cells per well. The cells were then cultured for four hours in a medium for cell culture (trade name: D-MEM (1 g/L glucose), manufactured by Wako Pure Chemical Industries) supplemented with 10% bovine fetal serum (herein below, referred to as a “standard medium”) in a 5% CO 2  and saturated water vapor atmosphere at 37° C. (degrees Celsius). For the evaluation of an antioxidant effect on AAPH, antibiotics (penicillin, streptomycin, and fungizone) were supplemented to the standard medium and the cells were cultured for one day. 
     2-2. Medium for Evaluation of Antioxidant Effect 
     Subsequently, the culture medium was switched to a medium for cell culture (trade name: D-MEM (1 g/L glucose), manufactured by Wako Pure Chemicals Industries) supplemented with 0.5% bovine fetal serum (herein below, referred to as “low-serum medium”) to which 0.01% or 0.05% carnosine, or 0.1 μM (micro-molar) or 10 μM (micro-molar) D- or L-aspartic acid had been added, and the cells were cultured for two days under atmosphere of 5% CO 2  and saturated moisture at 37° C. (degrees Celsius). For the experiment for the evaluation of oxidative damages on AAPH, the culture medium was switched to the medium for cell culture to which 5 ppm or 100 ppm carnosine, or 10 μM (micro-molar) D- or L-aspartic acid had been further added, and the cells were cultured for two days. The low-serum medium described above to which neither carnosine nor aspartic acid had been added was employed as a negative control. 
     2-3. Addition of Oxidant 
     After culturing for two days, 1 mM or 4 mM hydrogen peroxide, or 50 mM or 100 mM AAPH was added to the medium for evaluating an antioxidant effect, and the antioxidant effect was evaluated for carnosine or aspartic acid. The low-serum medium described above to which neither hydrogen peroxide nor AAPH had been added was employed as a control for evaluation of toxicity of an antioxidant when no oxidant was added. 
     2-4. Quantification of Oxidative Damages 
     Two hours after the addition of hydrogen peroxide or AAPH, AlarmarBlue (trade name: Biosource, manufactured by Biosource International Inc.) was added to have final concentration of 10%. Two to three hours later, according to the methods by Ahmed S. A. et al. (J. Immunol. Method., 170, 211-224 (1994)) and the instructions provided by the manufacturer, the fluorescent intensity of the supernatant was measured with an excitation wavelength of 544 nm, and an emission wavelength of 590 nm. 
     3. Results 
     3-1. Antioxidant Effect of Carnosine on Hydrogen Peroxide 
       FIG. 1  shows the results of the experiment obtained by examining the antioxidant effect of carnosine on hydrogen peroxide in Cryo NHDF-Neo cells. The error bars for each experimental condition indicate the standard deviations of the experimentally measured values obtained by repeating the experiment three times under the identical condition. The asterisk (*) indicates that t is less than 5% by Bonferroni/Dunn test. 
     The ratio of viable cells for the control group for evaluating toxicity of the antioxidant without addition of an oxidant was 102% when carnosine had not been added. When the concentration of carnosine was 0.01%, it was 100%. When the concentration of carnosine was 0.05%, it was 97%. The ratio of viable cells in the case of addition of 1 mM hydrogen peroxide was 45% when carnosine had not been added. When the concentration of carnosine was 0.01%, it was 51%. When the concentration of carnosine was 0.05%, it was 53%. The ratio of viable cells in the case of 4 mM hydrogen peroxide was 14% when carnosine had not been added. When the concentration of carnosine was 0.01%, it was 21%. When the concentration of carnosine was 0.05%, it was 45%. Thus, when the concentration of hydrogen peroxide was 4 mM, a significant difference in the ratio of viable cells was observed for the case in which 0.05% carnosine had been added compared to the ratio without addition of carnosine. Based on the results above, the antioxidant effect of carnosine on hydrogen peroxide was confirmed in the experiment system of the present example.

     The ratio of viable cells for the control group for evaluating toxicity of an antioxidant without addition of an oxidant was 93% when L-aspartic acid had not been added. When the concentration of L-aspartic acid was 0.1 μl (micro-molar), it was 88%. When the concentration of L-aspartic acid was 10 μM (micro-molar), it was 97%. The ratio of viable cells in the case of 1 mM hydrogen peroxide was 61% when L-aspartic acid had not been added. When the concentration of L-aspartic acid was 0.1 μM (micro-molar), it was 62%. When the concentration of L-aspartic acid was 10 μM (micro-molar), it was 62%. The ratio of viable cells in the case of 4 mM hydrogen peroxide was 36% when L-aspartic acid had not been added. When the concentration of L-aspartic acid was 0.1 μM (micro-molar), it was 33%. When the concentration of L-aspartic acid was 10 μM (micro-molar), it was 32%. Based on the results above, a statistically significant antioxidant effect of L-aspartic acid on hydrogen peroxide was not observed. 
     3-3. Antioxidant Effect of D-Aspartic Acid on Hydrogen Peroxide 
       FIG. 3  shows the results of the experiment obtained by examining the antioxidant effect of D-aspartic acid on oxidative damages induced by hydrogen peroxide in Cryo NHDF-Neo cells. The error bars for each experimental condition indicate the standard deviations of experimentally measured values obtained by repeating the experiment three times under the identical condition. The asterisk (*) indicates that p is less than 5% by Bonferroni/Dunn test. The double asterisk (**) indicates that p is less than 1% by Bonferroni/Dunn test. 
     The ratio of viable cells for the control group for evaluating toxicity of an antioxidant without addition of an oxidant was 97% when D-aspartic acid had not been added. When the concentration of D-aspartic acid was 0.1 μM (micro-molar), it was 86%. When the concentration of D-aspartic acid was 10 μM (micro-molar), it was 97%. In the case of 1 mM hydrogen peroxide, the ratio of viable cells was 55% when D-aspartic acid had not been added. When the concentration of D-aspartic acid was 0.1 μM (micro-molar), it was 62%. When the concentration of D-aspartic acid was 10 μM (micro-molar), it was 63%. In the case of 4 mM hydrogen peroxide, the ratio of viable cells was 22% when D-aspartic acid had not been added. When the concentration of D-aspartic acid was 0.1 μM (micro-molar), it was 29%. When the concentration of D-aspartic acid was 10 μM (micro-molar), it was 34%. Thus, when the concentration of hydrogen peroxide was 4 mM, a significant difference in the ratio of viable cells was observed for the case in which 0.1 μM (micro-molar) or 10 μM (micro-molar) D-aspartic acid had been added compared to the ratio without addition of D-aspartic acid. Based on the results above, the concentration-dependent antioxidant effect of D-aspartic acid on hydrogen peroxide was observed.

     The ratio of viable cells for the control group for evaluating toxicity of an antioxidant without addition of an oxidant was 100% when carnosine had not been added. When the concentration of carnosine was 5 ppm, it was 93%. When the concentration of carnosine was 100 ppm, it was 103%. The ratio of viable cells in the case of 100 mM AAPH was 31% when carnosine had not been added. When the concentration of carnosine was 5 ppm, it was 60%. When the concentration of carnosine was 100 ppm, it was 85%. When AAPH had concentration of 100 mM, a significant difference was observed for the ratio of viable cells for the case in which carnosine had been added at the concentration of 100 ppm compared to the ratio without addition of carnosine. Based on the results above, the antioxidant effect of carnosine on AAPH was confirmed by the experiment system of the present example. 
     3-5. Antioxidant Effect of L- and D-Aspartic Acids in Experiment for Evaluating Oxidative Damages Induced by AAPH 
       FIG. 5  shows the experiment obtained by examining the antioxidant effect of L- and D-aspartic acids in the experiment for evaluating oxidative damages induced by AAPH in Cryo NHDF-Neo cells. The error bars for each experimental condition indicate the standard deviations of the experimentally measured values obtained by repeating the test three times under the identical condition. The asterisk (*) indicates that p is less than 5% by Bonferroni/Dunn test. The triple asterisk (***) indicates that p is less than 0.1% by Bonferroni/Dunn test. 
     The ratio of viable cells for the control group for evaluating toxicity of an antioxidant without addition of the oxidant was 95% when L- and D-aspartic acids had not been added. When the concentration of D-aspartic acid was 10 μM (micro-molar), it was 102%. When the concentration of L-aspartic acid was 10 μM (micro-molar), it was 80%. In the case of 100 mM AAPH, the ratio of viable cells was 51% when L- and D-aspartic acids had not been added. When the concentration of D-aspartic acid was 10 μM (micro-molar), it was 96%. When the concentration of L-aspartic acid was 10 μM (micro-molar), it was 69%. When AAPH had concentration of 100 mM, a significant difference was observed for the ratio of viable cells for the case in which L- and D-aspartic acids had been added at concentration of 10 μM (micro-molar) compared to the ratio without addition of L- and D-aspartic acids. Based on the results above, it was indicated that D-aspartic acid had more potent antioxidant effect on AAPH compared to L-aspartic acid. 
     4. Conclusions 
     Based on the experimental results of the Examples above, D-aspartic acid was found to have an antioxidant effect on both hydrogen peroxide and AAPH. However, L-aspartic acid was found to have an antioxidant effect on AAPH only. Thus, it was indicated that D-aspartic acid is effective against both hydroxyl radical and a peroxyl radical, but L-aspartic acid is effective only against a peroxyl radical.

Method for Producing Formulation Example 11 (Bean Paste)
 
     Malted rice is mixed thoroughly with a salt. Washed soybeans are soaked overnight in three times its volumes of water, which are then drained off, and new water is added while boiling, and poured into a colander to collect the broth (tanemizu fluid), to which aspartic acid is dissolved at 10% w/v. The boiled beans are minced immediately, combined with malted rice mixed with salt, to which the tanemizu fluid containing aspartic acid dissolved therein is added and kneaded evenly to obtain a clay-like hardness. Dumplings are made and stuffed in a container compactly without forming any voids, and the surface of the content is smoothened and sealed with a plastic film. After three months, the content is transferred to a new container and the surface is smoothened and sealed with a plastic film. Instead of adding aspartic acid to the tanemizu fluid, a malted rice producing a large amount of aspartic acid may be employed. Such malted rice can be selected by quantifying aspartic acid by the method described in Japanese Patent Unexamined Publication No. 2008-185558. Alternatively, a commercially available bean paste can be supplemented with aspartic acid or a salt thereof.
