L-Glutamine
L-Glutamine is a naturally occurring amino acid and one of the most abundant amino acids in the human body. It plays a crucial role in various physiological processes, including protein synthesis, cell proliferation, and immune function. L-Glutamine is commonly used as a supplement in cell culture media to support the growth and viability of mammalian cells in vitro. It provides essential nitrogen and carbon sources for cell metabolism and is particularly important for rapidly dividing cells, such as those in cancer research or biopharmaceutical production.
