L-谷氨酰胺

L-Glutamine is a conditionally essential amino acid. It is the most abundant free amino acid in mammalian plasma and intracellular fluids, playing a central role in nitrogen metabolism and biosynthetic pathways. Structurally, L-Glutamine is the γ-amide of glutamic acid, featuring an amide group in its side chain that enables it to function as a major nitrogen donor in a variety of metabolic reactions.

L-谷氨酰胺是一种必需氨基酸，作为细胞培养过程中主要的能量来源而成为培养基的重要组分。L-谷氨酰胺在干粉及冷冻溶液的状态下极为稳定。然而，L-谷氨酰胺在液体培养基或储存溶液中均会相对较快的降解。最佳的细胞表现通常需要在使用前向培养基中添加L-谷氨酰胺补充剂。
