DescriptionProstaglandin F2b, also known as PGF2B or 9b,11a-PGF2a, belongs to the class of organic compounds known as prostaglandins and related compounds. These 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. Thus, prostaglandin F2B is considered to be an eicosanoid lipid molecule. pgf(sub 2-β) is found in Gracilaria gracilis and Homo sapiens. pgf(sub 2-β) was first documented in 1975 (PMID: 1105694). Prostaglandin F2b is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral (PMID: 14504139) (PMID: 364547).
