(adsbygoogle = window.adsbygoogle || []).push({}); Vitamin B1 is also known as thiamine belongs to water-soluble vitamins of B complex. They oxidize thiamine. One of the first symptoms of thiamine deficiency is a loss of appetite (anorexia). Read on to know more about the structure and functions of TPP… Beriberi is divided into "dry beriberi" and "wet beriberi". With a shortage of vitamin B1, the thiamin deficiency disease develops wich is known as beriberi. It functions as a catalyst in the generation of energy through decarboxylation of branched-chain amino acids and alpha-ketoacids and acts as a coenzyme for transketolase reactions in the form of thiamine pyrophosphate. In this form, the vitamin B1 function is related to the activation of ion transport in nerve cells and may be involved in neurotransmission by regulating sodium channels and acetylcholine receptors. This review covers the recent advances in enzyme catalyzed asymmetric C–C bond formation using the most pronounced thiamine pyrophosphate dependent enzymes: acetohydroxyacid synthase, benzaldehyde lyase, benzoylformate decarboxylase, pyruvate … In 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.
