Tlhaloso ea Lihlahisoa
Thiamine kapa thiamine kapa vithamine B1 e bitsoang "thio-vitamine" ("vithamini e nang le sebabole") ke vithamine e qhibilihang ka metsing ea B complex. Ea pele e bitsoang aneurin bakeng sa litlamorao tse mpe tsa methapo haeba e le sieo lijong, qetellong e ile ea fuoa lebitso le hlalosang ka kakaretso vithamine B1. Li-derivatives tsa eona tsa phosphate li ameha lits'ebetsong tse ngata tsa cellular. Sebopeho se tsebahalang ka ho fetesisa ke thiamine pyrophosphate (TPP), coenzyme ka har'a catabolism ea tsoekere le li-amino acid. Thiamine e sebelisoa ho biosynthesis ea neurotransmitter acetylcholine le gamma-aminobutyric acid (GABA). Ka tomoso, TPP e boetse e hlokahala mohatong oa pele oa ho belisoa ha joala.
