A fat has -

Options

A. 3 glycerol and one fatty acid molecule
B. One glycerol and 3 fatty acid molecules
C. 3 glycerol and 3 fatty acid molecules
D. One glycerol and one fatty acid molecule

Answer

To answer the question regarding the structure of fats, we need to analyze the components that make up fats, specifically triglycerides.

### Step-by-Step Solution:

1. **Understanding the Components of Fats**: Fats are primarily composed of glycerol and fatty acids. Glycerol is a three-carbon alcohol, and fatty acids are long hydrocarbon chains with a carboxylic acid group.

2. **Identifying the Structure of Triglycerides**: The most common type of fat found in the body is triglycerides. A triglyceride molecule consists of one glycerol molecule and three fatty acid molecules.

3. **Analyzing the Options**:
- **Option 1**: 3 glycerol and 1 fatty acid - This is incorrect as fats do not have multiple glycerol molecules.
- **Option 2**: 1 glycerol and 3 fatty acids - This is correct and represents the structure of triglycerides.
- **Option 3**: 3 glycerol and 3 fatty acids - This is incorrect; fats do not have multiple glycerol molecules.
- **Option 4**: 1 glycerol and 1 fatty acid - This is incorrect as it does not represent the typical structure of fats.

4. **Conclusion**: The correct answer is that a fat has **1 glycerol and 3 fatty acids**.

### Final Answer:
A fat has **1 glycerol and 3 fatty acids**.
