Biochemistry of Malondialdehyde


Malondialdehyde is the amoebic admixture with the blueprint CH2(CHO)2. The anatomy of this breed is added circuitous than this blueprint suggests. This acknowledging breed occurs by itself and is a brand for oxidative stress.
Reactive oxygen breed abase polyunsaturated lipids, basic malondialdehyde. This admixture is a acknowledging aldehyde and is one of the abounding acknowledging electrophile breed that could cause baneful accent in beef and anatomy covalent protein adducts referred to as avant-garde lipoxidation end-products (ALE), in affinity to avant-garde glycation end-products (AGE). The assembly of this aldehyde is acclimated as a biomarker to admeasurement the akin of oxidative accent in an organism.
Malondialdehyde reacts with deoxyadenosine and deoxyguanosine in DNA, basic DNA adducts, the primary one getting M1G, which is mutagenic.The guanidine accumulation of arginine residues abbreviate with malondialdehyde to accord 2-aminopyrimidines.
Human ALDH1A1 aldehyde dehydrogenase is able of acerbic malondialdehyde.
Analysis:

Malondialdehyde and added thiobarbituric acknowledging substances (TBARS) abbreviate with two equivalents of thiobarbituric acerbic to accord a beaming red acquired that can be assayed spectrophotometrically. 1-Methyl-2-phenylindole is an another added careful reagent.
