It is nonessential amino acid which is synthesized from branched chain amino acids (BCAAs) by transamination requiring the enzyme glutamine synthase.
L-Glutamine makes up approximately 50-60% of the free amino acid within cells but less than 10% of the structural protein within skeleton muscle.
L-Glutamine provides an important contribution muscle growth through protein synthesis an increased growth hormone levels in a recent study by the American Journal of Clinical Nutrition.
In American Journal of Clinical Nutrition 1995, scientists reported that a single 2-gram dose of L-Glutamine can elevated circulating growth hormone levels by over 430%.
Growth hormone is responsible for glucose and amino acid uptake within the body, muscle growth due to protein synthesis and the utilization of fat stores for energy.
L-Glutamine is present in large amounts in the lining of the digestive tract. When muscles or the lining of the intestinal tract are damaged, glutamine plays a vital role in the process that fixes the damage.
It can be exceptionally useful in cases of food poisoning or infection through is action to slow diarrhea. In general it slows down transit time by restoring mucosal function.
L-Glutamine is metabolized to glutamate, aspartame, lactate and pyruvate and is a substrate for the production of glutathione which is important in antioxidant intracellular defense mechanisms.
