As they are hydrophobic in nature, lipids and fat prevents water to stick on the surface of plants and animals.

Explanation

4 classes of lipid are:

  1. Triglycerides.
  2. These are the molecule produced by esterification of fatty acid with glycerol.

    It includes palmitic acid, oleic acid.

  3. Phospholipid.
  4. A phospholipid consisting of tail which is hydrophobic in nature while polar head is hydrophilic in nature contains phosphate group.

    It includes phosphatidylinositol-(4, 5)-bisphosphate

  5. Steroid...
