what are the characteristics ester
In chemistry, esters are chemical compounds derived from an acid (organic or inorganic) in which at least one-OH (hydroxyl) group is replaced by an-O- alkyl (alkoxy) group. Usually, esters are derived from a carboxylic acid and an alcohol.Glycerides, which are fatty acid esters of glycerol, are important esters in biology, being one of the main classes of lipids, and making up the bulk of animal fats and vegetable oils.s a class, esters serve as protecting groups for carboxylic acids. Protecting a carboxylic acid is useful in peptide synthesis, to prevent self-reactions of the bifunctional amino acids. Methyl and ethyl esters are commonly available for many amino acids; the t-butyl ester tends to be more expensive.
Esters are formed by the reaction of an alcohol and a carboxylic acid, usually in the presence of sulfuric acid to catalyse the process, or by the reaction of an acyl chloride â¦ with a carboxylic acid (this requires no catalyst and is irreversible without additional reactants) are the most common ways used.o, esters are neutral and they are organic compounds that result from the interaction of acids and alcohol. The presence of esters can cause the fruity-ish flavors and arom â¦ as, such as banana, blueberry, rasberry and pear, that intentionally or unintentionally occur in some beers.
Esters can also be derived from an inorganic acid and an alcohol. Thus, the nomenclature extends to inorganic oxo acids, e.g. phosphoric acid, sulfuric acid, nitric acid and boric acid. For example, triphenyl phosphate is the ester derived from phosphoric acid and phenol.s a class, esters serve as protecting groups for carboxylic acids.
