Tag: Steroid nucleus

Cholesterol, an essential component of animal cell membranes, contains exactly one carbon-carbon double bond. This single double bond, located within the B-ring of its steroid nucleus, is a key structural feature that influences the molecule's overall shape and function within the body.

Steroids are organic compounds that are hydrophobic and insoluble in water, despite having a structure that differs from other lipids. They are defined by a characteristic core structure, known as the steroid nucleus or gonane. Thousands of different steroid molecules found in nature share this fundamental architecture.
