What is MDA (Malondialdehyde)?

MDA is the by-product in the lipid peroxidation reaction of unsaturated fatty acids with free radicals. Intact MDA molecule can bind biological molecules and thereby reduce the biochemical functions of the molecules. Most of the MDA molecules, produced in an organism, are secreted and degraded ultimately to nontoxic metabolites. However, excessive production of MDA in an organism leaves undegraded MDA in the system. The undegraded MDA can be measured in the urine specimen of such an individual. Thus, MDA concentration in urine specimen may represent the biological indicators to assess the degree of oxidative damage occurred in the subject. As a result, it’s vital to regularly check and monitor the free radical activity in the body via self-stick FR strips.
