First, isolated and characterized in 1900 by Gulewitsch, carnosine ([beta]-alanyl-L-hystidine) is a dipeptide, which commonly presents in mammalian tissue, and in particular, in skeletal muscle cells; it is responsible for a variety of activities related to the detoxification of the body from free radical species and the byproducts of membrane lipids peroxidation, but recent studies have shown that this small molecule also has membrane protecting activity, proton buffering capacity, formation of complexes with transition metals, and regulation of macrophage function (6).
