Description Biochem/physiol Actions L-Anserine s a dipeptide found in most animal tissues. In model systems it is a potent antioxidant and scavener of hydroxyl radicals. It inhibits nonenzymatic protein glycation induced by aldose and ketose reducing sugars. It is much less potent than L-carnosine as an inhibitor of protein-protein crosslinking. Linkage Anserine is a naturally occurring methylated analog of carnosine.
