L-Carnosine |305-84-0
Ibisobanuro ku bicuruzwa:
Carnosine (L-Carnosine), izina ry'ubumenyi β-alanyl-L-histidine, ni dipeptide igizwe na β-alanine na L-histidine, ikomeye ya kirisiti.Imitsi nubwonko birimo ubwinshi bwa karnosine.Carnosine yavumbuwe na chimiste w’Uburusiya Gurevich hamwe na karnitine.
Ubushakashatsi bwakorewe mu Bwongereza, Koreya y'Epfo, Uburusiya no mu bindi bihugu bwerekanye ko karnosine ifite imbaraga za antioxydeant kandi ifitiye umubiri w'umuntu.
Carnosine yerekanwe gukuramo radicals ya ogisijeni ikora (ROS) na α-β aldehydes idahagije yakozwe mugihe cya stress ya okiside ikoresheje aside irike ikabije ya selile.
Kugena ubudahangarwa:
Ifite ingaruka zo kugenzura ubudahangarwa, kandi irashobora kugenga indwara zabarwayi bafite hyperimmunite cyangwa hypoimmunite.
Carnosine irashobora kugira uruhare runini mugutunganya iyubakwa ryinzitizi yumubiri wumuntu, yaba ubudahangarwa bwimikorere cyangwa ubudahangarwa bwurwenya.
Endocrine:
Carnosine irashobora kandi kugumana uburinganire bwa endocrine yumubiri wumuntu.Ku bijyanye n'indwara za endocrine na metabolike, kuzuza neza karnosine birashobora kugabanya urwego rwa endocrine mu mubiri.
Kugaburira umubiri:
Carnosine ifite kandi uruhare runini mu kugaburira umubiri, ushobora kugaburira ubwonko bw'umuntu, kunoza imikurire y'ubwonko bwa neurotransmitter, no kugaburira imitsi ya nervice, ishobora kugaburira neurone no kugaburira imitsi.
