Anserine (beta-alanyl-3-methyl-histidine) is a urinary biomarker from the consumption of poultry and fish. It is a dipeptide consisting of the amino acids 1-methylhistidine and beta-alanine. The enzyme carnosineN-methyl transferase catalyzes the transfer of a methyl group of S-adenosylmethionine (SAM) on carnosine to form anserine. Anserine acts as an antioxidant, free radical scavenger, and pH buffer. It can reduce blood sugar and affect renal sympathetic nerve activity and blood pressure. Anserine is measured in FMV urine only.
