Describe various forms of lipid with a few examples.

Explanation

### Step-by-Step Text Solution

**Step 1: Definition of Lipids**
Lipids are organic compounds primarily made up of carbon, hydrogen, and oxygen atoms. They play crucial roles in the structure and function of living cells. One of the key characteristics of lipids is that they are insoluble in water, which distinguishes them from other biomolecules.

**Step 2: Structure of Lipids**
Lipids typically have a structure consisting of a polar head and non-polar tails. The polar head is hydrophilic (water-attracting), while the tails are hydrophobic (water-repelling). This unique structure allows lipids to form various biological membranes and structures.
