lipids
Cell membrane components
Lipids are a broad class of organic compounds that include fats, oils, waxes, and related substances.
They share the property of being insoluble in water but soluble in organic solvents.
In biology, lipids serve as energy storage, structural components of cell membranes, and signaling molecules.
The term encompasses familiar substances like cholesterol and triglycerides, which appear regularly in discussions of diet and health.
