Popis: Glutamine, a non-essential amino acid, is widely abundant in the body and in the food we eat. In times of stress it is released from skeletal muscle and acts as an interorgan nitrogen and carbon transporter. It is an important energy source directly to many cells and indirectly through glycogen metabolism. It is fundamental for protein synthesis, where it donates nitrogen for the synthesis of purines, pyrimidines, nucleotides and amino sugars, and is a precursor for the synthesis of the major antioxidant, glutathione. The kidney, liver, small intestine and cells of the immune system all use glutamine. Over the long term, the liver and immune systems predominate and use glutamine for synthetic processes and immune modulation.
