Cyclohexane

Definition

Cyclohexane is a colorless, flammable liquid organic compound with the molecular formula C6H12, characterized by its six-membered carbon ring structure. This compound is significant in the context of lipids as it serves as a non-polar solvent and is a structural component in the synthesis of various lipids and fatty acids. Its stable chair conformation minimizes steric strain, making it an important model compound for studying cyclic hydrocarbons and their behavior in biological systems.
