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.

Ọ nwere mmetụta nke ịchịkwa mgbochi, ma nwee ike ịchịkwa ọrịa nke ndị ọrịa nwere hyperimmunity ma ọ bụ hypoimmunity.
Carnosine nwere ike ịrụ ọrụ dị oke mma n'ịhazi iwu ihe mgbochi mgbochi mmadụ, ma ọ bụ mgbochi cellular ma ọ bụ ihe mgbochi ihu ọchị.
Endocrine:
Carnosine nwekwara ike idobe nguzozi endocrine nke ahụ mmadụ. N'ihe banyere ọrịa endocrine na ọrịa metabolic, mgbakwunye kwesịrị ekwesị nke carnosine nwere ike ịhazi ọkwa endocrine n'ime ahụ.
Na-edozi ahụ:
Carnosine nwekwara ọrụ ụfọdụ n'ịkwalite ahụ ahụ, nke nwere ike inye anụ ahụ ụbụrụ mmadụ nri, kwalite uto nke ụbụrụ neurotransmitters, na-edozi njedebe akwara, nke nwere ike ịzụ neurons na iri nri irighiri akwara.
