Glutamine (Glu or E)
Amino acid-Functions-Glutamine
- Oxidative substrate for immune cells and IECs
- A precursor for glutamate/GSH
- Intestinal growth, structure, and function (young animals and disease states)
- Supports proliferative rates and reduces apoptosis of IECs
- Protects against E.coli/LPS-induced damage to the intestinal structure and barrier function
- Lowers inflammatory and increases immunoregulatory cytokine production
- Improves the proliferative responses of IELs and MLN cells
- Intestinal IgA levels
- Increases lymphocyte numbers in PP, lamina propria, and IELs
Glutamine:
- Glutamic acid is one of the 20 proteinogenic amino acids. It is a non-essential amino acid.
Glutamine Synthetase:
- Most tissues, including muscle, have glutamine synthetase, which captures excess nitrogen by aminating glutamate to form glutamine. The reaction is irreversible. Glutamine, a relatively nontoxic substance, is the major carrier of excess nitrogen from tissues.
- Glutamine synthase converts NH3 to nontoxic glutamine. Glutaminase releases NH3 for use in urea synthesis.
Glutaminase:
- The kidney contains glutaminase, allowing it to deaminate glutamine arriving in the blood and to eliminate the amino group as ammonium ion in urine. The reaction is irreversible.
- Kidney glutaminase is induced by chronic acidosis, in which excretion of ammonium may become the major defense mechanism. The liver has only small quantities of glutaminase; however, levels of the enzyme are high in the intestine where the ammonium ion from deamination can be sent directly to the liver via the portal blood and used for urea synthesis.
- The intestinal bacteria and glutamine from dietary protein contribute to the intestinal ammonia entering the portal blood.
Aminotransferases (Transaminases):
- Both muscle and liver have aminotransferases, which, unlike deaminases, do not release the amino groups as free ammonium ion. This class of enzymes transfers the amino group from one carbon skeleton (an amino acid) to another (usually a-ketoglutarate, a citric acid cycle intermediate). Pyridoxal phosphate (PLP) derived from vitamin B6 is required to mediate the transfer.
- Aminotransferases are named according to the amino acid donating the amino group to a-ketoglutarate. Two important examples are alanine aminotransferase (ALT, formerly GPT) and aspartate aminotransferase (AST, formerly GOT). Although the aminotransferases are in liver and muscle, in pathologic conditions these enzymes may leak into the blood, where they are useful clinical indicators of damage to liver or muscle.
Glutamate Dehydrogenase:
- This enzyme is found in many tissues, where it catalyzes the reversible oxidative deamination of the amino acid glutamate. It produces the citric acid cycle intermediate a-ketoglutarate, which serves as an entry point to the cycle for a group of glucogenic amino acids. Its role in urea synthesis and nitrogen removal is still controversial.
Uses:
- Calming effect, its made into gamma-aminobutyric acid (GABA), a neurotransmitter in the central nervous system.
- In 1 person in 10, glutamine can act as a stimulant because it can be made into glutamic acid, which sends signals that excite the nerves rather than calming them. The worst that can happen is a restless night's sleep.
- Wound healing-Boosts depressed immunity.
- Breaking addictions to caffeine and other stimulants.
- May also help treat diarrhea that is caused by gluten intolerance, Crohn's disease, AIDS, knowing within 3 days if it is working.
Cancer cells:
- Like an acidic environment and glutamine help shift the body chemistry in the other direction, an alkaline environment.
Glutamic Acid:
- May relieve symptoms of a type of prostate problem in men called benign prostatic hyperplasia (BPH).
D-Glutamine:
- A non-essential amino acid present abundantly throughout the body and is involved in many metabolic processes. It is synthesized from glutamic acid and ammonia. It is the principal carrier of nitrogen in the body and is an important energy source for many cells.
