Epoxide group

An epoxide is a functional group derived from the ether group. In fact, it is a cyclic ether, forming a ring with 3 members (2 carbons and 1 oxygen). The cyclic structure is an equilateral triangle and presents a high rigidity and structural tension.

In biochemistry, epoxides are important molecules in many metabolic processes, such as, for example, in the synthesis of cholesterol.
