Description of Glutamine Powder
- Aug 15, 2019 -

Glutamine powder is the most abundant free amino acid in human body. 

It is not only a regulator of DNA synthesis, an important energy source for RNA synthesis in mucosal cells, but also an important fuel for many immune cells in the immune system. Exercise affects the level of glutamine powder in the free amino acid pool, and changes in glutamine powder level react with immune cells, resulting in a series of chain reactions. Glutamine powder participates in many metabolic processes in the body and has attracted wide attention in the treatment and prevention of some diseases. Although glutamine powder is classified as a non-essential amino acid, in severe trauma, major surgery, sepsis, bone marrow transplantation, intensive chemotherapy and radiotherapy, endogenous synthetic glutamine powder can not meet its own needs, and even lead to the depletion of glutamine powder in vivo, which must be supplemented by exogenous sources, which makes it a conditionality. Essential amino acids. Glutamine powder is one of the most abundant amino acids in body fluids. Its content in blood is as high as 500-900 micromol/L. 50-60% of the free amino acid pool in vivo is glutamine powder. Glutamine-binding peptide is a dipeptide or polypeptide formed by glutamine powder and other amino acids. Its solubility and stability are better than glutamine powder. Aminoamide monomers are unstable under acidic conditions and are easy to produce toxic pyroglutamic acid by heating. Therefore, traditional amino acid intravenous injection or nutrient solution does not contain glutamine powder. In recent years, glutamine powder has gradually become a research hotspot in nutrition, physiology and other disciplines due to its unique and complex physiological functions. Some physiological functions of glutamyl dipeptides and polypeptides are basically the same as those of glutamine powder. Glutamine-binding peptides have good application prospects in medicine, functional food and special feed.



Glutamine powder is produced during protein digestion in the intestinal cavity, but this part of glutamine powder hardly enters the blood. The small intestinal absorption cells utilize glutamine powder at a high rate, and almost all the glutamine powder absorbed by the intestinal cavity is utilized. Therefore, the body must provide additional glutamine powder to meet the extremely high needs of the immune system. The main site of glutamine production is skeletal muscle. Evidence is as follows: (1) skeletal muscle contains high concentration of glutamine powder; (2) skeletal muscle has the enzymes needed to synthesize glutamine powder; (3) skeletal muscle has been known to release glutamine powder at a high rate. The synthesis of glutamine powder in skeletal muscle begins with the deamination of branched-chain amino acids and the transfer of amino acids to ketoacid to produce glutamic acid, which is further aminated by a carboxyl group of glutamic acid catalyzed by glutamine synthetase to produce glutamine powder.
