The correct Answer is:
### Step-by-Step Solution: 1. **Understanding Lecithin**: Lecithin is a substance that is often categorized in the context of lipids. It is important to identify its classification correctly. 2. **Types of Lipids**: Lipids can be classified into three main categories: - Simple Lipids (or Simple Fats) - Complex Lipids (or Complex Fats) - Derivative Lipids 3. **Focus on Complex Lipids**: Lecithin falls under the category of complex lipids. Complex lipids are formed by combining fats with other molecules. 4. **Examples of Complex Lipids**: - Glycolipids: Formed when fats are attached to carbohydrates. - Proteolipids: Formed when fats are attached to proteins. - Phospholipids: Formed when fats are attached to phosphate groups. 5. **Identifying Lecithin**: Lecithin is specifically a phospholipid, which means it is a complex lipid that includes a phosphate group in its structure. 6. **Structure of Lecithin**: The structure of lecithin consists of: - A glycerol backbone. - Two fatty acid chains. - An inorganic phosphate group attached to the glycerol. 7. **Conclusion**: Based on the classification and structure, lecithin is identified as a phospholipid. ### Final Answer: Lecithin is a **Phospholipid**. ---

[A] : In the embryos liver is haemopoietic, it produces red blood corpuscles (R803). The breakdown products of haemoglobin of de- stroyed RBCs are converted into bile pigment to be eliminated with faeces. [R]: The main function of liver is secretion of bile, which has bile pigments, cholesterol and lecithin.
