evidence: Thiobarbituric acid reactive substances - TBARS - are formed as a byproduct of lipid peroxidation -LRB- i.e. as degradation products of fats -RRB- which can be detected by the TBARS assay using thiobarbituric acid as a reagent .. lipid peroxidation. lipid peroxidation. TBARS assay. TBARS assay. thiobarbituric acid. thiobarbituric acid. Because reactive oxygen species -LRB- ROS -RRB- have extremely short half-lives , they are difficult to measure directly .. reactive oxygen species. Reactive Oxygen Species. Instead , what can be measured are several products of the damage produced by oxidative stress , such as TBARS .. Assay of TBARS measures malondialdehyde -LRB- MDA -RRB- present in the sample , as well as malondialdehyde generated from lipid hydroperoxides by the hydrolytic conditions of the reaction .. malondialdehyde. malondialdehyde. MDA is one of several low-molecular-weight end products formed via the decomposition of certain primary and secondary lipid peroxidation products .. lipid peroxidation. lipid peroxidation. However , only certain lipid peroxidation products generate MDA , and MDA is neither the sole end product of fatty peroxide formation and decomposition , nor a substance generated exclusively through lipid peroxidation .. lipid peroxidation. lipid peroxidation. These and other considerations from the extensive literature on MDA , TBA reactivity , and oxidative lipid degradation support the conclusion that MDA determination and the TBA test can offer , at best , a narrow and somewhat empirical window on the complex process of lipid peroxidation .. lipid peroxidation. lipid peroxidation. Use of MDA analysis and / or the TBA test and interpretation of sample MDA content and TBA test response in studies of lipid peroxidation require caution , discretion , and -LRB- especially in biological systems -RRB- correlative data from other indices of fatty peroxide formation and decomposition .. lipid peroxidation. lipid peroxidation
