Choose a saturated fatty acid from the following compounds.

Options

A. Palmitic acid
B. Linoleic acid
C. Oleic acid
D. Arachidonic acid

Answer

To determine which of the given compounds is a saturated fatty acid, we need to understand the definition of saturated and unsaturated fatty acids.

### Step-by-Step Solution:

1. **Definition of Saturated Fatty Acids**:
- Saturated fatty acids are characterized by having no double bonds between the carbon atoms in their hydrocarbon chain. This means that all carbon atoms are fully "saturated" with hydrogen atoms.

2. **Identifying the Options**:
- We have four options to analyze:
- **Palmitic Acid**
- **Linoleic Acid**
- **Oleic Acid**
- **Arachidonic Acid**

3. **Analyzing Each Option**:
- **Palmitic Acid**: This fatty acid has a straight-chain structure with no double bonds. Therefore, it is a saturated fatty acid.
- **Linoleic Acid**: This fatty acid contains two double bonds in its structure, which makes it unsaturated.
- **Oleic Acid**: This fatty acid has one double bond, indicating that it is also unsaturated.
- **Arachidonic Acid**: This fatty acid has four double bonds, confirming that it is unsaturated.

4. **Conclusion**:
- Among the options provided, **Palmitic Acid** is the only saturated fatty acid.

### Final Answer:
The saturated fatty acid from the given compounds is **Palmitic Acid**.
