Metabolite Identification
Common NamePro-Ile
DescriptionPro-ile, also known as L-pro-L-ile or PI, 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. Pro-ile is possibly soluble (in water) and a very strong basic compound (based on its pKa).
