WebThiamine pyrophosphate (TPP) provides the biochemical and enzymological answer. TPP is the key catalytic cofactor used by enzymes catalyzing non-oxidative and oxidative decarboxylation of α-keto acids. Pyruvate, for example, undergoes both types of decarboxylation, both involving TPP. Thiamine is one of the B vitamins and is also known as vitamin B1. It is a cation that is usually supplied as a chloride salt. It is soluble in water, methanol and glycerol, but practically insoluble in less polar organic solvents. In the body, thiamine can form derivatives; the most well-characterized of which is thiamine pyrophosphate (TPP), a coenzyme in the catabolism of sugars and amino acids. The chemical structure consists of an aminopyrimidine and a thia… Thiamine is one of the B vitamins and is also known as vitamin B1. It is a cation that is usually supplied as a chloride salt.
