Glucogenic amino acid
From Wikipedia, the free encyclopedia
A glucogenic amino acid is an amino acid that can be converted into glucose through gluconeogenesis.[1][2] This is in contrast to the ketogenic amino acids that are converted into ketone bodies.
In humans, the glucogenic amino acids are - glycine, serine, valine, histidine, arginine, cysteine, proline, alanine, glutamate, glutamine, aspartate, asparagine and methionine. The ketogenic amino acids are leucine and lysine, while threonine, isoleucine, phenylalanine, tyrosine and tryptophan can feed into either system.
