Thiamine or thiamin or vitamin B1 (/ˈθaɪ.əmᵻn/ THY-ə-min), named as the "thio-vitamine" ("sulfur-containin vitamin") is a watter-soluble vitamin o the B complex. First named aneurin for the detrimental neurological effects if nae present in the diet, it wis eventually assigned the generic descriptor name vitamin B1. Its phosphate derivatives are involved in mony cellular processes. The best-characterized furm is thiamine pyrophosphate (TPP), a coenzyme in the catabolism o succars an amino acids. Thiamine is uised in the biosynthesis o the neurotransmitter acetylcholine an gamma-aminobutyric acid (GABA). In baurm, TPP is an aa required in the first step o alcoholic fermentation.
Aw livin organisms uise thiamine, but it is synthesized anly in bacteria, fungi, an plants. Ainimals must obtain it frae thair diet, an thus, for them, it is an essential nutrient. Insufficient intake in birds produces a characteristic polyneuritis. In mammals, deficiency results in Korsakoff's syndrome, optic neuropathy, an a disease cried beriberi that affects the peripheral nervous seestem (polyneuritis) an/or the cardiovascular seestem. Thiamine deficiency haes a potentially fatal ootcome if it remains untreatit.[1] In less severe cases, nonspecific signs include malaise, wicht loss, irritability an confusion.[2]
