Thiamine thiazolone pyrophosphate
WebIn its diphosphate form (also known as TDP, thiamine pyrophosphate, TPP, or cocarboxylase), it serves as a cofactor for enzymes involved in carbohydrate metabolism, including transketolase, α-ketoglutarate dehydrogenase, pyruvate dehydrogenase, and branched chain α-keto acid dehydrogenase. WebThiamine diphosphate (TPP) is another very important coenzyme which, like PLP, acts as an electron sink to stabilize key carbanion intermediates. The important part of the TPP …
