Definition of Steroids: Steroids are a class of organic compounds characterized by a core structure of 17 carbon atoms arranged in four fused rings: three cyclohexane rings (A, B, and C) and one cyclopentane ring (D). This core structure, known as the “steroid nucleus” or “cyclopentanoperhydrophenanthrene ring system,” serves as …

Lipids: Definition, classification with examples
Lipids are a diverse group of organic molecules that are characterized by their hydrophobic (water-insoluble) nature. They are an essential class of biological macromolecules, along with proteins, nucleic acids, and carbohydrates. Lipids serve various crucial roles in living organisms, including energy storage, structural components of cell membranes, insulation, and signaling …
Lipids- Definition, Classification, Nature, Role
Lipids constitute diverse organic molecules essential to living cells’ structure and function. They play critical roles in energy storage, insulation, protection, and signaling within biological systems. Lipids are hydrophobic, meaning they are not soluble in water. Classification of LIpids Lipids are broadly classified into several categories: Lipids are a diverse …
