Metabolite Identification
Common NameMethylgeranate
DescriptionMethylgeranate is also known as methylgeranic acid. Methylgeranate is slightly soluble (in water) and a very weakly acidic compound (based on its pKa). Methylgeranate can be found in papaya, which makes methylgeranate a potential biomarker for the consumption of this food product.
