Phosphatidyl choline is an example for
Derived lipid
Conjugated lipid
Simple lipid
Steroids

Options

A. Derived lipid
B. Conjugated lipid
C. Simple lipid
D. Steroids

Answer

To determine the classification of phosphatidyl choline, we need to analyze the different types of lipids and their characteristics. Here’s a step-by-step breakdown of the solution:

### Step 1: Understand the Types of Lipids
- **Simple Lipids**: These are primarily fats and oils, which are esters of glycerol and fatty acids. They serve as energy storage in organisms.

### Step 2: Identify Derived Lipids
- **Derived Lipids**: These are products of the hydrolysis of simple lipids. For example, fatty acids and glycerol are derived from the breakdown of fats.

### Step 3: Explore Conjugated Lipids
- **Conjugated Lipids**: These are complex lipids that contain additional components such as carbohydrates or proteins. Phospholipids, which include phosphatidyl choline, fall under this category. They are crucial for forming cell membranes.

### Step 4: Examine Steroids
- **Steroids**: These are a class of lipids characterized by a carbon skeleton with four fused rings. Cholesterol is a well-known example of a steroid.

### Step 5: Identify Phosphatidyl Choline
- Phosphatidyl choline is a phospholipid, which is a type of conjugated lipid. It contains a phosphate group and is essential for cell membrane structure and function.

### Conclusion
Based on the analysis, phosphatidyl choline is classified as a **conjugated lipid**.

### Final Answer
The correct option is **Conjugated lipid**.
