<s>[INST] context: vitamin B 1 - water soluble vitamin It has a specific coenzyme TPP (thiamine pyrophosphate ) this help in carbohydrate metabolism . TPP Dependent enzyme pyruvate dehydrogenase - conversion of pyruvate to acetyl CoA. alpha -Ketoglutarate dehydrogenase - CTA CYCLE Transketolas - (HMP shunt) The branched chain ALPHA - keto acid dehydrogenase -: oxidative decarboxylation pyrophosphate of branched chain amino acids . RDA ( Recommended dietary allowance) Adult - 1 - 1.5 mg/day Children - 0.7 - 1.2 mg /day The requirement increases in pregnancy and lactation (2 mg/ day), old age and alcoholism.
