introduction | thiamine pyrophosphate (TPP) is a coenzyme form of vitamin B1 (thiamine), which is formed by phosphorylation of vitamin B1 (thiamine). Thiamine pyrophosphate TPP is a coenzyme involved in the synthesis and cleavage of carbonyl carbon (aldehyde, ketone) in sugar metabolism, especially the decarboxylation of α-keto acid. Thiamine pyrophosphate passes through the N = C active site The carbon atom combines with the α-carbon atom (carbonyl carbon atom) to promote the cleavage of the carboxyl group to release carbon dioxide. |
physiological functions and effects | thiamine pyrophosphate (Thiamine Pyrophosphate, TPP) is a metabolite of vitamin B1, a cofactor synthesized in cytosol, and is necessary to maintain the activity of cytosol transketase and mitochondrial pyruvate, ketoglutaric acid and branched keto acid dehydrogenase. TPP can be used to evaluate the mechanism of deacidification in biological systems. TPP can also prevent hyperglycemia-induced retinopathy and desflurane-induced hepatotoxicity in rats. |
application | thiamine pyrophosphate is a white crystalline powder, which can be used for biochemical research. It is clinically used to treat arrhythmia, myocardial infarction, coma and other diseases. |
precautions | thiamine pyrophosphate is sensitive to light and heat. the dry powder of this product is stable, but the aqueous solution is very unstable. it is recommended to use it now. It is only used for scientific research purposes, never for clinical diagnosis or therapeutic drugs, never for food or drugs. |
use | biochemical research; clinically used to treat arrhythmia, myocardial infarction, coma and other diseases. |
production method | thiamine hydrochloride reacts with phosphoric acid, and then is prepared by hydrochloric acid treatment. |
