Description_x000D_ General description_x000D_ Glutamine is a non-essential and the most abundant free amino acid present in the human body. It is an important component of proteins and is one of the 20 proteinogenic amino acids. It forms 5-6% of bound amino acids._x000D_ Application_x000D_ D-Glutamine has been used to study its role in conferring protection against acetaldehyde-induced disruption of barrier function in Caco-2 cell monolayer._x000D_ Packaging_x000D_ 1, 5, 10 g in poly bottle_x000D_ Biochem/physiol Actions_x000D_ Glutamine forms the central metabolite in amino acid transamination via a-ketoglutarate and glutamic acid. This amino acid is metabolized by different enzymes, such as glutaminase, present in liver, and glutamine synthetase, present in skeletal muscle. It is produced in the cytoplasm from other amino acids, predominantly from branched-chain amino acids and glutamate. It plays an essential role in ammonia metabolism and detoxification. Its skeletal muscle levels are significantly reduced post trauma, operation and inflammatory states. It servers as a prognostic marker in fatal sepsis during which its skeletal muscle levels are decreased by 90%._x000D_ Other Notes_x000D_ Unnatural isomer of glutamine
