Biological active form is Thiamine pyrophosphate (TPP). Acts as a coenzyme in several metabolic reactions. * Acts as coenzyme to the enzyme pyruvate dehydrogenase complex (PDH) which conves pyruvic acid to acetyl-CoA (oxidative decarboxylation) Pyruvate PDH TPP Acetyl-CoA * Similarly acts as a coenzyme to a-oxoglutarate dehydrogenase complex and conves a-oxoglutarate to succinyl-CoA (oxidative decarboxylation). a-oxoglutarate dehydrogenase a-Oxoglutarate TPP Succinyl-CoARef: MN Chatterjea Textbook of Medical Biochemistry, 6th Edition, Page no: 178
