无臭;有引湿性。本品在水中易溶,在甲醇中几乎不溶或不溶;在冰醋酸中略溶。在哺乳动物细胞培养基中可以作谷氨酸盐的替代物,加热灭菌过程中稳定。 L-Glutamine is an essential supplement for cell culture. The free amino acid L-glutamine is unstable and degrades to pyroglutamate. Alanyl-L-glutamine (Ala-Gln) and Gylcyl-L-glutamine (Gly-Gln) are used in cell culture as alternative delivery forms of stabilized L-glutamine. The primary advantage of using L-alanylglutamine in place of L-glutamine is that it reduces the level of ammonia generated during cell culture
