In fact, though, the decarboxylation of a β-keto acid and the decarboxylation of mevalonate 5-diphosphate are closely related.

Carbon 1 is called the head of the molecule; carbon 4 is called the tail. Since the isoprene molecule has five carbon atoms, the number of carbon atoms in the molecule of a terpene/terpenoid is a multiple of five. The difference between terpenes and terpenoids is that terpenes are hydrocarbons, whereas terpenoids contain oxygen.

They play crucial roles in various physiological processes, including inflammation, pain, fever, and regulation of blood flow. Prostaglandins are synthesized through cyclooxygenase enzymes, leading to diverse biological effects. Eicosanoids can also influence immune responses and are implicated in numerous diseases.

Not only does the identity of the side group have an influence (such as the sulfonate group, SO 3 - , or an amine group, NH 2 , in an azo dye), but the group's exact position is important as well.
