Ester of animalwax derived from a various carboxylic acids and alcohols. As they are hydrophobic in nature, lipids and fat prevents water to stick on the surface of plants and animals.

Explanation

Lipids are water insoluble substances. They can be extracted from the cells by different organic solvents such as benzene. There are 4 classes in which the lipids can be divided:

  1. Fats.
  2. Phospholipids.
  3. Waxes.
  4. Steroids.

This classification is molecular structural based...
