GENETICS Terms Amino Acid Glutamine

 

- Info:

- Glutamine chemical formula is C5H10N2O3.

- Glutamine is non-essential amino acid which means that humans can synthesise it.

- 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 .
