What is Alpha-Ketoglutarate?

Other names: AKGα-KG, 2-oxoglutarate2OG

Alpha-Ketoglutarate is an organic acid that is important for the proper metabolism of all essential amino acids. It is formed in the Krebs cycle, the energy-producing process that occurs in most body cells.

The Krebs cycle (aka Citric Acid cycle) is a series of chemical reactions used by all aerobic organisms to release stored energy through the oxidation of acetyl-CoA derived from carbohydrates, fats, and proteins into ATP.

AKG (alpha-ketoglutarate) is the nitrogen-free portion of the amino acids known as glutamine and glutamic acid, which is involved in protein synthesis that may play a role in supporting healthy blood glucose levels. Alpha-ketoglutarate (AKG) helps maintain normal levels of ammonia in the brain, muscles and kidneys, as well as the body’s nitrogen balance in body tissues and fluids.

AKG is used by cells during growth and in healing from injuries and other wounds, and is especially important in the healing of muscle tissue.

α-Ketoglutarate is one of the most important nitrogen transporters in metabolic pathways. The amino groups of amino acids are attached to it (by transamination) and carried to the liver where the urea cycle takes place.

High urine levels of alpha-KG can be found in people with hyperinsulinism-hyperammonemia syndrome (HHS).
