Vitamin B1 | 67-03-8
Khoom Description
Thiamine los yog thiamine los yog vitamin B1 hu ua "thio-vitamine" ("sulfur-muaj vitamin") yog dej-soluble vitamin ntawm B complex. Thawj lub npe hu ua aneurin rau kev puas tsuaj rau lub paj hlwb yog tias tsis muaj nyob rau hauv cov khoom noj, nws thiaj li tau muab lub npe piav qhia lub npe vitamin B1. Nws cov phosphate derivatives koom nrog ntau cov txheej txheem ntawm tes. Daim ntawv zoo tshaj plaws yog thiamine pyrophosphate (TPP), coenzyme hauv catabolism ntawm suab thaj thiab amino acids. Thiamine yog siv rau hauv biosynthesis ntawm neurotransmitter acetylcholine thiab gamma-aminobutyric acid (GABA). Nyob rau hauv cov poov xab, TPP kuj yuav tsum tau nyob rau hauv thawj kauj ruam ntawm cawv fermentation.
