Sharaxaada Alaabta
Thiamine ama thiamin ama fiitamiin B1 oo lagu magacaabo "thio-fitamiin" ("fitamiin baaruud ku jira") waa fiitamiinada B ee isku dhafan ee biyaha ku milma. Markii ugu horreysay ee loogu magac daray aneurin ee waxyeellada neerfaha haddii aysan ku jirin cuntada, waxaa ugu dambeyntii loo qoondeeyay magaca sharraxaadda guud ee fitamiin B1. Soosaarkeeda fosfooraska ayaa ku lug leh hawlo badan oo gacanta ah. Qaabka ugu wanaagsan ee lagu sifeeyay waa thiamine pyrophosphate (TPP), oo ah coenzyme ku jirta catabolismka sonkorta iyo amino acids. Thiamine waxaa loo isticmaalaa biosynthesis ee neurotransmitter acetylcholine iyo gamma-aminobutyric acid (GABA). Khamiirka, TPP ayaa sidoo kale looga baahan yahay tallaabada ugu horreysa ee halsano khamriga.
