· GENETICS – Terms – Amino Acid – Glutamine
- Glutamine chemical formula is C5H10N2O3.
- Glutamine is non-essential amino acid which means that humans can
- Glutamine 'R' group is -(CH2)2-CO-NH2, an ethyl group with an amide
group attached. An amide group is a carbonyl
group (-C=O) - grey, with red - attached to another amino group - blue
with 2 whites - at the other end of the molecule.
- Glutamine is converted to glutamic acid in the brain, which is
essential for cerebral functions, and increases the amount
of GABA (gamma-aminobutyric acid), which is required for brain
functioning and mental activity.
Glutamine is used in the muscles for the synthesis of muscle proteins,
and is of use for the treatment of wasting muscles
after illness or post-operative care.
Body requires nitrogen but free nitrogen in the body can be harmful
since it forms ammonia which is toxic to the brain.
Glutamine attaches itself to nitrogen and forms glutamic acid, while
removing ammonia from the brain.
Liver converts ammonia to urea, excreted in the urine .
