Carnosine (beta-alanyl-L-histidine) and homocarnosine (gamma-aminobutyryl-L-histidine) are abundant dipeptides in skeletal muscle and brain of most vertebrates. Carnosine synthase 1 (CARNS1) transforms ATP, L-histidine (L-His) and beta-alanine (b-Ala) to carnosine (CARN) with much greater efficiency than synthesis of homocarnosine (Drozak et al. 2010).
