Prostaglandins and thrombosis formation

Abstract

As a group, postaglandins (PG) are composed of a pentagonal carbonring with oxygensubstitutes and two long parallel carbonchains. According to the precise composition of the pentane ring, they are called by the letters A until I (for instance: prostaglandin F), the subscript numeral points to the number of double bonds in the side chain (for instance: F₁) and a Grecian letter shows there exist isomers (for instance: Prostaglandin F₁), All prostaglandins proceed from essential fatty acids with 20 carbon atoms.
