Chemical Information
FooDB NameProstaglandin E-2
DescriptionProstaglandin e-2 is a member of the class of compounds known as prostaglandins and related compounds. Prostaglandins and related compounds are unsaturated carboxylic acids consisting of a 20 carbon skeleton that also contains a five member ring, and are based upon the fatty acid arachidonic acid. Prostaglandin e-2 is practically insoluble (in water) and a weakly acidic compound (based on its pKa). Prostaglandin e-2 can be found in soft-necked garlic, which makes prostaglandin e-2 a potential biomarker for the consumption of this food product.

oxytocic36063 A drug that stimulates contraction of the myometrium. Oxytocics are used to induce labour, obstetric at term, to prevent or control postpartum or postabortion haemorrhage, and to assess foetal status in high risk pregnancies. They may also be used alone or with other drugs to induce abortions (abortifacients).DUKE
