Thiamine (Vitamin B1) is a water-soluble vitamin and an important constituent of TPP (thiamine pyrophosphate), a cofactor found in several important dehydrogenase reactions.

Specifically, TPP is an important cofactor for pyruvate dehydrogenase (see Pyruvate Metabolism), α-ketoglutarate dehydrogenase, and branched-chain ketoacid dehydrogenase (see Maple Syrup Urine Disease). Besides dehydrogenase reactions, TPP also serves an important role as a cofactor for transketolase.
