Anserine (β-alanyl-N-methylhistidine) is a dipeptide containing β-alanine and 1-methylhistidine, which can be found in the skeletal muscle and brain of mammals and birds.

The pKa of the imidazole ring of histidine, when contained in anserine, is 7.04, making it an effective buffer at physiologic pH.
