The number of fatty acid molecules in trigly ceride is

Options

A. One
B. Two
C. Three
D. Four

Answer

To determine the number of fatty acid molecules in a triglyceride, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Triglycerides**:
- Triglycerides are a type of lipid and are the main form of stored energy in the body. They are composed of one glycerol molecule and three fatty acid molecules.

2. **Structure of Triglycerides**:
- A triglyceride is formed by the esterification of one glycerol molecule with three fatty acid chains. The glycerol molecule has three hydroxyl (-OH) groups that react with the carboxyl (-COOH) groups of fatty acids to form ester bonds.

3. **Counting Fatty Acids**:
- Since each triglyceride molecule is formed from one glycerol and three fatty acids, we can conclude that there are three fatty acid molecules in one triglyceride.

4. **Conclusion**:
- Therefore, the number of fatty acid molecules in a triglyceride is **3**.

### Final Answer:
The number of fatty acid molecules in a triglyceride is **3**.
