Natural Product Identification
Common Nameprostaglandin b2
DescriptionProstaglandin B2, also known as PGB2, 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 B2 is considered to be an eicosanoid lipid molecule. Prostaglandin B2 is a very hydrophobic molecule, practically insoluble (in water), and relatively neutral. prostaglandin b2 is found in Homo sapiens, Larix sibirica and Sarcophyton crassocaule. In humans, prostaglandin B2 is involved in mefenamic acid action pathway.
