carnosine

A dipeptide composed of beta-alanine and histidine that is concentrated in skeletal muscle and the brain. While its function is unknown, carnosine has antioxidant properties, counteracts glycation, chelates divalent metal ions and acts as a buffer, stabilising the pH of anaerobically contracting muscle.
