glucogenic amino acid
A glucogenic amino acid is an amino acid that can be converted into glucose through gluconeogenesis. This is in contrast to the ketogenic amino acids, which are converted into ketone bodies.
The production of glucose from glucogenic amino acids involves these amino acids being converted to alpha keto acids and then to glucose, with both processes occurring in the liver. This mechanism predominates during catabolysis, rising as fasting and starvation increase in severity.
In humans, the glucogenic amino acids are:
* Glycine
* Serine
* Valine
* Histidine
* Arginine
* Cysteine
* Proline
* Alanine
* Glutamate
* Glutamine
* Aspartate
* Asparagine
* Methionine
Amino acids that are both glucogenic and ketogenic (mnemonic "PITTT"):
* Phenylalanine
* Isoleucine
* Threonine
* Tyrosine
* Tryptophan
Only leucine and lysine are not glucogenic (they are only ketogenic).
