Glutamine-S 39537-23-0 Large in supply CAS NO.39537-23-0

property this product appears as white or almost white crystalline powder, being odorless; has hygroscopicity; being easily soluble in water, almost insoluble in the methanol and only slightly soluble in glacial acetic acid.
pharmacological effects this product is an integral part of parenteral nutrition, n (2)-l-alanyl-l-glutamine can be broken down into glutamine and alanine in the body. its characteristics is that it can supplement glutamine through parenteral nutrition infusion; the released amino acids of this kinds of dipeptide can be stored in the corresponding parts of the body as a nutrient and metabolized in response to the demands of the body. for symptoms that can possibly cause in vivo glutamine depletion, the goods can be supplemented for parenteral nutrition support.
pharmacokinetics n (2)-l-alanyl-l-glutamine is subject to rapid decomposition into glutamine and alanine in vivo with its human half-life of 2.4 to 3.8 minutes (being 4.2 minutes for late renal dysfunction patients), and the plasma elimination rate was 1.6 to 2.7 l/min. the disappearance of this dipeptide is accompanied by an increase in the number of free amino acids of equal molar number. its hydrolysis process may only occur in the extracellular. when the infusion volume is constant, n (2)-l-alanyl-l-glutamine excreted through the urine is less than 5%, being identical to the other infused amino acids.
uses this product is an integral part of parenteral nutrition and is indicated for patients who require supplementation with glutamine, including those in catabolic and metabolic conditions. such as: trauma, burns, large and medium-sized operation, bone marrow and other organ transplantation, gastrointestinal syndrome, cancer, severe infection and other stressful icu patients. this product is a supplement to the amino acid solution. upon application, it should be supplemented into other amino acid solution or infusion containing amino acids.
it is a kind of dipeptide used as the glutamine substituents in mammalian cell culture media; glutamine is unstable in solution with the formed ammonia having deleterious effects in cell culture; ala-glu is stable against thermal disinfection, having a smaller effect of ammonia formation than glutamine. as one of the components of the medium, it is advantageous to exert its advantages
