What is Glutamine?

Glutamine (Gln) is the most abundant free amino acid in animal blood and body tissues, and it is an important nutrient. Glutamine has always been regarded as a non-essential amino acid, but recent studies have shown that Under stress or pathological conditions, endogenous glutamine often cannot meet the needs of the animal body, and even glutamine depletion occurs. Therefore, it has been proposed that glutamine is a conditionally essential amino acid. In NRC (1998), Glutamine has been defined as a “conditionally essential amino acid”.

Glutamine is a multifunctional nutrient that plays an important role in livestock and poultry breeding.

Glutamine is a conditionally essential amino acid. It is an important energy substance for intestinal mucosal epithelial cells, lymphocytes, mononuclear macrophages, renal tubular epithelial cells and fibroblasts. The metabolites of glutamine can be used as precursors for the synthesis of important substances in life, such as purines, amino acids, proteins, and nucleic acids. Therefore, its nutritional and pharmacological effects have attracted more and more attention.

And because glutamine is closely related to immune function, especially the intestinal immune barrier function, as a new type of feed additive, its application prospects have also attracted much attention.
