[Biological role of histidine-containing dipeptides].

The biological role of histidine-containing dipeptides is reviewed. The role of carnosine and anserine in muscle function is discussed from the evolutionary viewpoint. Evidence on the antioxidative effect of carnosine and its protection of biological membranes against lipid peroxidation-induced damages is presented. The effects of presently known natural antioxidative agents and carnosine on lipid peroxidation are compared. Carnosine has been shown to be a more universal protector of membranes as compared to free radical scavengers.
