Number of fatty acids present in a molecule of phospholipid is

Options

A. Two
B. Three
C. One
D. None.

Answer

To determine the number of fatty acids present in a molecule of phospholipid, we can follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Phospholipids**:
- Phospholipids are composed of a glycerol backbone, two fatty acid tails, and a phosphate group.

2. **Identify the Components**:
- The glycerol molecule has three hydroxyl (OH) groups.
- In phospholipids, two of these hydroxyl groups are esterified with fatty acids.

3. **Count the Fatty Acids**:
- Since two hydroxyl groups are linked to fatty acids, this means there are two fatty acid chains in a phospholipid molecule.

4. **Conclusion**:
- Therefore, the number of fatty acids present in a molecule of phospholipid is 2.

### Final Answer:
The number of fatty acids present in a molecule of phospholipid is **2**.
