Metabolite Identification
Common NameCucurbitin
DescriptionCucurbitin 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). Cucurbitin is soluble (in water) and a moderately acidic compound (based on its pKa). Cucurbitin can be found in cucumber and muskmelon, which makes cucurbitin a potential biomarker for the consumption of these food products. Cucurbitin is an amino acid and a carboxypyrrolidine that is found in Cucurbita seeds. Cucurbitin causes degenerative changes in the reproductive organs of parasitic flatworms called flukes .
