The glutamic acid-glutamine interconversion is of central importance to the regulation of the levels of toxic ammonia in the body, and it is thus not surprising that when the concentrations of the amino acids of blood plasma are measured, glutamine is found to have the highest of all. Glutamine can donate the ammonia on its side chain to the formation of urea urea (y

The German chemist Emil Fischer did much of the basic work on purines and introduced the term into the chemical literature in the early 20th cent.

Once glutamine is incorporated into proteins, its relatively unreactive side-chain amide participates in very few reactions. Glutamine is not essential to the human diet, since it can be synthesized in the body from glutamic acid. Glutamine was isolated from beet juice in 1883, but was not isolated from a protein until 1932; it was chemically synthesized in 1933.

glutamine
One of the nonessential amino acids, closely related to glutamic acid. It is especially important in the cellular metabolism of animals as the only amino acid capable of readily crossing the blood-brain barrier. It is used in medicine and biochemical research and as a feed additive.
