A typical fat molecule is made up of

Options

A. One glycerol and three fatty acid molecules
B. One glycerol and one fatty acid molecule
C. Three glycerol and the three fatty acid molecules
D. Three glycerol molecules and one fatty acid molecule

Answer

To answer the question about what a typical fat molecule is made up of, we can break it down into the following steps:

### Step-by-Step Solution:

1. **Understanding Fat Molecules**: A typical fat molecule, also known as a triglyceride, is a type of lipid. It is essential to know that fat molecules are primarily composed of two main components: glycerol and fatty acids.

2. **Identifying the Components**:
- **Glycerol**: This is a small organic molecule that serves as the backbone of the fat molecule. It contains three hydroxyl (–OH) groups, which are important for forming ester bonds with fatty acids.
- **Fatty Acids**: These are long hydrocarbon chains that are attached to the glycerol backbone. In a typical fat molecule, there are three fatty acid chains.

3. **Combining the Components**: A typical fat molecule is formed by one glycerol molecule and three fatty acid molecules. The fatty acids can vary in length and saturation (saturated or unsaturated), but the structure remains consistent with one glycerol and three fatty acids.

4. **Conclusion**: Therefore, the correct answer to the question is that a typical fat molecule is made up of **1 glycerol and 3 fatty acid molecules**.

### Final Answer:
A typical fat molecule is made up of **1 glycerol and 3 fatty acid molecules**.
