L-Carnitine | 541-15-1
Incazelo Yemikhiqizo
I-L-carnitine, ngezinye izikhathi ebizwa ngokuthi i-carnitine nje, iwumsoco owenziwe ku-amino acids methionine ne-lysine esibindi nezinso futhi ugcinwe ebuchosheni, enhliziyweni, ezicubu zemisipha, nesidoda. Abantu abaningi bakhiqiza inani elanele lalesi sakhi ukuze bahlale bephilile. Kodwa-ke, izifo ezithile zezokwelapha zingavimbela i-carnitine biosynthesis noma zivimbele ukusatshalaliswa kwayo kumaseli wezicubu, njenge-claudication ephakathi, isifo senhliziyo, kanye nokuphazamiseka okuthile kofuzo. Eminye imithi ingase futhi ithinte kabi i-carnitine metabolism emzimbeni.Umsebenzi oyinhloko we-L-carnitine ukuguqula i-lipids, noma amafutha, abe nguphethiloli wamandla.
Ngokukhethekile, indima yayo ukuhambisa ama-fatty acids ku-mitochondria yamaseli e-eukaryotic ahlala ngaphakathi kolwelwesi oluvikelayo oluzungeza amangqamuzana. Lapha, ama-fatty acids angena kwi-beta oxidation futhi ahlehle akheke i-acetate. Lesi senzakalo yiso esiqala umjikelezo we-Krebs, uchungechunge lwezinqubo eziyinkimbinkimbi zezinto eziphilayo ezibalulekile ukuze kunikezwe amandla kuwo wonke amangqamuzana emzimbeni.L-carnitine nayo idlala indima ekulondolozeni amathambo. Ngeshwa, lesi sakhi sincipha kancane emathanjeni kanye ne-osteocalcin, iphrotheni ekhishwa ama-osteoblasts ebandakanyeka ekwakhiweni kwamathambo. Eqinisweni, lokhu kusilela yizici eziyinhloko ezibangela ukukhumuzeka kwamathambo kwabesifazane abangemva kokuya esikhathini. Ucwaningo luye lwabonisa ukuthi lesi simo singahlehliswa nge-L-carnitine supplementation, okwandisa amazinga atholakalayo e-osteocalcin.
Ezinye izinkinga ezingase zibhekane nokwelashwa kwe-L-carnitine zihlanganisa ukusetshenziswa okuthuthukisiwe kwe-glucose kubantu abanesifo sikashukela, izimpawu ezincishisiwe ezihlobene nesifo sokukhathala okungapheli, nokulawulwa kwe-thyroid okuthuthukisiwe kubantu abane-hyperthyroidism. Kukhona nobufakazi bokuthi i-propionyl-L-carnitine ingasiza ekuthuthukiseni ukungasebenzi kahle kwe-erectile emadodeni, kanye nokuthuthukisa ukusebenza kahle kwe-sidenafil, imithi ethengiswa ngaphansi kophawu lokuthengisa i-Viagra. Ngaphezu kwalokho, ucwaningo luye lwabonisa ukuthi lesi sakhi sithuthukisa inani lesidoda kanye ne-motility.
