NCIt definition : A dipeptide comprised of a beta-alanine and a 3-methyl-L-histidine, which is found
in dietary red meat, with potential antioxidant, metal-chelating and anti-glycation
activities. Carnosine scavenges both reactive oxygen species (ROS) and unsaturated
aldehydes produced by cell membrane lipid peroxidation. Additionally, this dipeptide
may reduce the rate of formation of advanced glycation end-products (AGE). Altogether,
this may protect cells against oxidative damage. In addition, carnosine is able to
chelate toxic metals.;
