L-Glutamine

First isolated from beet juice by Schulze in 1883, glutamine was later found in abundance in wheat gliadin. In 1935, Krebs described the synthesis of glutamine from ammonium and glutamate using the guinea pig and rat kidney.

Load 3D Structure of Glutamine

L-Glutamine is involved in more metabolic processes than any other amino acid. It is converted to glucose when more glucose is required by the body as an energy source. The amino acid also plays a part in maintaining proper blood glucose levels and the right pH range.
