Nkọwa ngwaahịa:
Carnosine (L-Carnosine), aha sayensị β-alanyl-L-histidine, bụ dipeptide nke mejupụtara β-alanine na L-histidine, nke siri ike kristal. Akwara ahụ na ụbụrụ ụbụrụ nwere nnukwu mkpụrụ nke carnosine. Carnosine bụ onye Russia chemist Gurevich chọtara ya na carnitine.
Nnyocha na United Kingdom, South Korea, Russia na mba ndị ọzọ egosila na carnosine nwere ikike antioxidant siri ike ma na-aba uru na ahụ mmadụ.
E gosiputara Carnosine iji weghachi ikuku oxygen radicals (ROS) na α-β unsaturated aldehydes guzobere n'oge nrụgide oxidative site n'ịfefe acid fatty acids na membranes cell.
