Lipids, Types, Structure and Examples

Context: According to a new study from the CSIR-Centre for Cellular and Molecular Biology (Hyderabad), lipids—fats in cells—also guide evolution by interacting closely with proteins, especially in cell membranes.

What are Lipids?

Lipids are fats that make up a major part of cell membranes.
They form the outer layer of cells, known as the cell membrane, along with proteins.
They are essential for various functions in living organisms, including energy storage, insulation, etc.
Lipids are insoluble in water but soluble in non-polar solvents.

Types of Lipids

Triglycerides (Fats and Oils): Major form of stored energy.
Phospholipids: Form the main structural component of cell membranes.
Steroids: Include cholesterol, which is a precursor to hormones.
Waxes: Found in plant cuticles and animal skin

Lipids differ in plants and animals

Plant lipids have kinkier tails due to polyunsaturated fatty acids → offer more flexibility.
Animal lipids have a straighter → more rigid structure.
