Metabolite Identification
Common NameBaikiain
DescriptionBaikiain, also known as 4,5-dehydropipecolic acid, (+-)-isomer, is a member of the class of compounds known as alpha amino acids. Alpha amino acids are amino acids in which the amino group is attached to the carbon atom immediately adjacent to the carboxylate group (alpha carbon). Baikiain is soluble (in water) and a moderately acidic compound (based on its pKa). Baikiain can be found in date, which makes baikiain a potential biomarker for the consumption of this food product.
