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.

Oxytocic 1185 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). Tumor promoter 1387 A role played by a chemical compound which is known to induce a process of carcinogenesis by corrupting normal cellular pathways, leading to the acquistion of tumoral capabilities.
