Anserine (beta-alanyl-N-methylhistidine) is a dipeptide found in the skeletal muscle and brain of mammals,[1] and birds.
It is an antioxidant (about 5 times that of carnosine) and helps reduce fatigue.[citation needed]
The pKa of the imidazole ring of histidine, when contained in anserine, is 7.04, making it an effective buffer at physiologic pH.[2]
