Description and Uses
2-Ketoglutaric acid also known as α-Ketoglutaric acid (AKG) is a chemical found in the body. It is a ketone derivative of the organic compound glutaric acid. It is important for the proper metabolism of all essential amino acids and the transfer of cellular energy in the citric acid or Krebs cycle. In combination with L-glutamate, AKG can reduce levels of ammonia formed in the brain, muscles, and kidneys, as well as help balance the body’s nitrogen chemistry and prevent nitrogen excess in body tissues and fluids.
α-Ketoglutaric acid is used for kidney disease; intestinal and stomach disorders, including bacterial infections; liver problems; cataracts; and recurring yeast infections. It is also used for improving the way kidney patients receiving hemodialysis treatments process protein.
2-Ketoglutaric acid has a wide range of applications in the animal feed, food, pharmaceutical and fine chemistry industries. It is used as an intermediate in the kreb's cycle catalyzed by glutamate dehydrogenase enzyme on glutamate. It is also used in dietary supplements to improve protein synthesis.
