Absorption and metabolism of taurine

2015-01-27 classification: efficacy 0 people commented that taurine is a sulfur-containing amino acid with small molecular weight, no antigenicity and easy absorption In recent years, the distribution, metabolism, nutritional function and mechanism of taurine have been studied The results show that taurine has a wide range of biological effects, such as promoting brain development, enhancing the ability of learning and memory, etc it is an important substance to regulate the normal physiological function of the body, and has a wide application value in production practice and people's life Part of taurine in the body combines with cholic acid to form bile, which can promote the digestion and absorption of fat soluble substances and lipids There are four main metabolic pathways of taurine in the body: ① taurocholate is produced in the liver with choline, which is excreted into the digestive tract with bile to promote the digestion and absorption of fat and lipid substances ② In the liver, carbamyl taurine is produced by transaminamide ③ Guanidine, which receives arginine, is catalysed by ATP guanidine transferase to form guanidine taurine, which is then phosphorylated to form guanidine taurine phosphate It can be used as a source of phosphoric acid in lower organisms and participate in the energy metabolism of the body ④ In the process of decomposition to sulfuric acid, the intermediate product ethyl thiamine is formed, which, together with taurine, regulates the transfer of ions through the biofilm Kidney is the main organ of taurine excretion, and it is mainly eliminated from urine in prototype The kidney can regulate the amount of taurine in accordance with the content of taurine in the body When taurine is excessive, the excess part will be excreted with urine When taurine is insufficient, the kidney can reduce the amount of taurine excretion through reabsorption to maintain the relative stability of taurine content in the rest Only a very small part of taurine can be converted into hydroxyethanesulfonic acid to be eliminated from urine During pregnancy and lactation, taurine excretion in urine decreased.
