Common NameL-alpha-amino-epsilon-keto-pimelate
DescriptionL-alpha-amino-epsilon-keto-pimelate belongs to alpha amino acids and derivatives class of compounds. Those are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon), or a derivative thereof. L-alpha-amino-epsilon-keto-pimelate is slightly soluble (in water) and a moderately acidic compound (based on its pKa). L-alpha-amino-epsilon-keto-pimelate can be found in a number of food items such as star fruit, cottonseed, black-eyed pea, and longan, which makes L-alpha-amino-epsilon-keto-pimelate a potential biomarker for the consumption of these food products.
