L-Glutamine is an essential amino acid required for cell metabolism. It is a crucial component of many cell culture media and serves as a major energy source for cells in culture.
L-Glutamine is very stable in powder and frozen solution form. However, in liquid media, L-Glutamine can degrade rapidly since it is more labile than other amino acids. Adding L-Glutamine extemporaneously to cell culture media enhances cell growth and metabolism.
