Q. Arachidonic acids is

Options

A. a) Non-essential fatty acid
B. b) Saturated fatty acid
C. c) Monousaturated fatty acid
D. d) Polyunsaturated fatty acid.

Answer

To determine what type of fatty acid arachidonic acid is, we can follow these steps:

### Step 1: Understand the Types of Fatty Acids
There are different classifications of fatty acids based on their structure:
- **Saturated Fatty Acids**: These have no double bonds between carbon atoms.
- **Monounsaturated Fatty Acids**: These contain one double bond in their structure.
- **Polyunsaturated Fatty Acids**: These have two or more double bonds in their structure.
- **Essential Fatty Acids**: These cannot be synthesized by the body and must be obtained through diet.

### Step 2: Identify Arachidonic Acid
Arachidonic acid is a fatty acid that is derived from linoleic acid. It is important to note that arachidonic acid is classified based on the number of double bonds present in its structure.

### Step 3: Analyze the Structure of Arachidonic Acid
Arachidonic acid has four double bonds in its structure. This characteristic makes it a polyunsaturated fatty acid.

### Step 4: Determine the Essentiality of Arachidonic Acid
Arachidonic acid is considered a non-essential fatty acid because it can be synthesized in the body from linoleic acid, which is an essential fatty acid.

### Conclusion
Based on the analysis, we can conclude that arachidonic acid is a **polyunsaturated fatty acid**.

### Final Answer
The correct option is **D. Polyunsaturated fatty acid**.
