C14H33N10O7PS (516.1992)

Phaseolotoxin is a member of the class of compounds known as oligopeptides. Oligopeptides are organic compounds containing a sequence of between three and ten alpha-amino acids joined by peptide bonds. Phaseolotoxin is practically insoluble (in water) and an extremely strong acidic compound (based on its pKa). Phaseolotoxin can be found in common bean, green bean, and yellow wax bean, which makes phaseolotoxin a potential biomarker for the consumption of these food products.
