Homocysteine (HCY)
Nkọwa
A na-eji Homocysteine (HCY) chọpụta homocysteine n'ime ọbara mmadụ.Homocysteine (Hcy) bụ amino acid nke nwere sọlfọ na-emepụta site na metabolism nke methionine.80% nke Hcy na-ejikọta na protein site na njikọ disulfide n'ime ọbara, ọ bụ naanị obere akụkụ nke homocysteine free na-ekere òkè na mgbasa.Ọkwa Hcy nwere njikọ chiri anya na ọrịa obi.bụ ihe dị mkpa dị ize ndụ maka ọrịa obi.Mmụba Hcy dị n'ọbara na-akpali mgbidi arịa ọbara ka ọ mebie arịa akwara, na-eduga na mbufụt na nhazi plaque na mgbidi arịa ahụ, nke na-emecha na-ebute nkwụsị nke ọbara n'ime obi.N'ime ndị ọrịa nwere hyperhomocystinuria, mmebi mkpụrụ ndụ ihe nketa siri ike na-emetụta metabolism Hcy, na-ebute hyperhomocysteinemia.Nrụrụ mkpụrụ ndụ ihe nketa dị nro ma ọ bụ ụkọ nri nke vitamin B ga-eso ya na mmụba dị oke ma ọ bụ dị nro nke Hcy, nke ga-abawanye ohere nke ọrịa obi.Hcy dị elu nwekwara ike ịkpata ntụpọ nwa dị ka ntụpọ akwara akwara na mmebi ọmụmụ.

Ụkpụrụ ule
A na-atụgharị Hcy Oxidized ka ọ bụrụ Hcy efu, na Hcy efu na-emeghachi omume na serine n'okpuru catalysis nke CBS iji mepụta L-cystathionine.L-cystathionine na-emepụta Hcy, pyruvate na NH3 n'okpuru catalysis nke CBL.Enwere ike ịchọpụta pyruvate sitere na mmeghachi omume okirikiri a site na lactate dehydrogenase LDH na NADH, na ngbanwe nke NADH na NAD dabara na ọdịnaya Hcy dị na nlele.
