Metabolite Identification
Common NameGlycylproline
DescriptionGlycylproline, also known as gly-pro, belongs to the class of organic compounds known as dipeptides. These are organic compounds containing a sequence of exactly two alpha-amino acids joined by a peptide bond. Glycylproline exists as a solid, possibly soluble (in water), and a very strong basic compound (based on its pKa) molecule. Glycylproline has been found to be associated with several diseases known as eosinophilic esophagitis, alzheimer's disease, and colorectal cancer; also glycylproline has been linked to the inborn metabolic disorders including prolidase deficiency.
