IiNkcazo zeeMveliso
I-Thiamine okanye i-thiamin okanye i-vitamin B1 ebizwa ngokuba yi-"thio-vitamine" ("i-vitamin equlethe i-sulphur") yivithamin enyibilikayo emanzini kwi-complex ye-B. Okokuqala yathiywa i-aneurin yeziphumo eziyingozi zemithambo-luvo ukuba ayikho ekutyeni, ekugqibeleni yanikwa igama lesichazi se-generic ye-vitamin B1. I-phosphate derivatives yayo ibandakanyeka kwiinkqubo ezininzi zeselula. Ifom ebonakaliswe kakhulu yi-thiamine pyrophosphate (TPP), i-coenzyme kwi-catabolism yeeshukela kunye ne-amino acids. I-Thiamine isetyenziswe kwi-biosynthesis ye-neurotransmitter acetylcholine kunye ne-gamma-aminobutyric acid (GABA). Kwigwele, i-TPP nayo iyafuneka kwinqanaba lokuqala lokubiliswa kotywala.
