The correct Answer is:
To answer the question "Lecithin is a:", we will analyze the characteristics and composition of lecithin step by step. ### Step-by-Step Solution: 1. **Understanding Lecithin**: Lecithin is a substance that is commonly found in various biological membranes and is important for cell structure and function. 2. **Composition of Lecithin**: Lecithin is primarily composed of fatty acids, glycerol, and phosphoric acid. This combination is crucial for its function in biological systems. 3. **Classification of Lecithin**: Lecithin is classified as a type of phospholipid. Phospholipids are a class of lipids that are a major component of all cell membranes. 4. **Exclusion of Other Options**: - **Simple Lipid**: Lecithin cannot be classified as a simple lipid because it contains additional components (phosphoric acid) that make it more complex. - **Dry Lipid**: This term is not applicable to lecithin as it is not a dry lipid. - **Steroid**: Lecithin does not fall under the category of steroids, which are a different class of lipids characterized by their four-ring structure. 5. **Conclusion**: Based on the composition and classification, the correct answer is that lecithin is a phospholipid. ### Final Answer: Lecithin is a phospholipid.
