Content of unsaturated fatty acids linolenic acid is highest in

Options

A. Sunflower oil
B. Cotton seed oil
C. Groundnut oil
D. Coconut oil.

Answer

To determine which oil has the highest content of the unsaturated fatty acid linoleic acid, we can follow these steps:

### Step 1: Understand Unsaturated Fatty Acids
Unsaturated fatty acids are those that contain one or more double bonds in their carbon chain. They are typically found in plant-based oils and are known to have health benefits, such as lowering blood cholesterol levels.

**Hint:** Remember that unsaturated fatty acids can be classified into monounsaturated (one double bond) and polyunsaturated (multiple double bonds).

### Step 2: Identify Linoleic Acid
Linoleic acid is a specific type of polyunsaturated fatty acid that contains two double bonds. It is essential for human health and must be obtained through diet.

**Hint:** Linoleic acid is often found in higher concentrations in certain plant oils.

### Step 3: Compare the Options
We are given four options to consider: sunflower oil, cottonseed oil, groundnut oil, and coconut oil. We need to evaluate which of these oils is known for having a high content of linoleic acid.

**Hint:** Think about common knowledge regarding the fatty acid composition of these oils.

### Step 4: Research or Recall Information
From nutritional data, it is known that sunflower oil is particularly high in linoleic acid compared to the other oils listed. Cottonseed oil and groundnut oil also contain linoleic acid, but not in as high a concentration as sunflower oil. Coconut oil, on the other hand, is primarily composed of saturated fatty acids.

**Hint:** If you have access to nutritional charts or databases, they can provide specific percentages of fatty acids in each oil.

### Step 5: Conclusion
Based on the information gathered, we conclude that the content of the unsaturated fatty acid linoleic acid is highest in sunflower oil.

**Final Answer:** The content of unsaturated fatty acid linoleic acid is highest in sunflower oil.
