I-L-carnosine (β-alanyl-L-histidine) yidipeptide ye-amino acids β-alanine kunye ne-histidine. Igxininiswe kakhulu kwizihlunu kunye nezicubu zengqondo. I-Carnosine ineentlobo ezahlukeneyo ze-antioxidant ezinokuba luncedo, ezinokususa iintlobo ze-oksijini ezisebenzayo kunye ne-α-β unsaturated aldehydes eyenziwe yi-fatty acid peroxidation yeembrane zeseli ngexesha loxinzelelo lwe-oxidative. I-Carnosine ikwayi-zwitterion, i-molecule engathathi hlangothi eneziphelo ezilungileyo nezimbi.
I-L-carnosine yi-dipeptide ene-antioxidant enamandla kunye ne-anti-glycation imisebenzi; iibhloko ze-non-enzymatic glycosylation kunye ne-protein cross-linking eyenziwa yi-aldehydes esebenzayo.

Izicelo zokutya
I-L-carnosine ayinakunqanda ngokufanelekileyo i-oxidation yamafutha, kodwa inokhuseleko oluphezulu kunye nemisebenzi yezempilo. Ngoko ke, i-L-carnosine yinto efanelekileyo yokutya i-antioxidant enexabiso lesicelo.
Izicelo zokuthambisa
Isetyenziswa kwizinto zokuthambisa, inokuthintela ukuguga kolusu kunye nokuba mhlophe kolusu. I-Carnosine inokuthintela iiradicals zasimahla ezenziwe kukutshaya, kwaye le radical yasimahla inokonakalisa ulusu ngaphezu kokukhanya kwelanga. Iiradicals zasimahla zisebenza kakhulu emzimbeni womntu. I-athomu okanye iqela le-athomu linokwenza i-oxidize ezinye izinto emzimbeni womntu.
Izicelo zamayeza
1. Ukongeza ekuvimbeleni inkqubo ye-peroxidation ye-membrane yeseli, i-carnosine inokuthintela uchungechunge lweempendulo ze-peroxidation kwiseli, oko kukuthi, i-carnosine inokuthintela yonke inyathelo le-oxidation reaction kulo lonke ikhonkco le-peroxidation kwi-organism;
