Fatty acid arachidonic acid is

Options

A. Monounsaturate
B. Biunsaturate
C. Triunsaturate
D. Tetra-unsaturate.

Answer

**Step-by-Step Text Solution:**

1. **Understanding Arachidonic Acid**: Arachidonic acid is a type of fatty acid that is important in various biological processes. It is often referred to as ARA.

2. **Identifying the Structure**: Arachidonic acid has a long carbon chain consisting of 20 carbon atoms.

3. **Counting Double Bonds**: The key feature of arachidonic acid is the presence of double bonds. Specifically, it contains four double bonds within its structure.

4. **Determining Saturation**: The term "unsaturated" refers to the presence of double bonds in the fatty acid chain. Since arachidonic acid has four double bonds, it is classified based on the number of these double bonds.

5. **Classifying Arachidonic Acid**: Given that arachidonic acid has four double bonds, it is classified as a "tetraunsaturated" fatty acid.

6. **Conclusion**: Therefore, the correct classification for arachidonic acid is that it is a tetraunsaturated fatty acid.

**Final Answer**: Arachidonic acid is a tetraunsaturated fatty acid.
