Anserine (Ans)

Anserine (Ans)
Anserine (beta-alanyl-N-methylhistidine) is a dipeptide found in the skeletal muscle and brain of mammals and birds. It is an antioxidant (about 5 times that of carnosine) and helps reduce fatigue. Carnosine, homocarnosine, and anserine are present in high concentrations in the muscle and brain of many animals and humans. However, their exact function is not clear. The antioxidant activity of these compounds has been examined by testing their peroxyl radical-trapping ability at physiological concentrations. Carnosine, homocarnosine, anserine, and other histidine derivatives all showed antioxidant activity. All of these compounds showing peroxyl radical-trapping activity were also electrochemically active as reducing agents in cyclic voltammetric measurements. Furthermore, carnosine inhibited the oxidative hydroxylation of deoxyguanosine induced by ascorbic acid and copper ions.
