Glycerides are also called neutral lipids because they

Options

A. dissolve in water to give neutral solutions
B. do not undergo hydrogenation
C. do not carry any charge
D. exist as zwitter ions in aqueous solutions

Answer

**Step-by-Step Solution:**

1. **Understanding Glycerides**: Glycerides are esters formed from glycerol and fatty acids. They are a type of lipid that plays a crucial role in biological systems.

2. **Definition of Neutral Lipids**: Glycerides are referred to as neutral lipids because they do not carry any charge. This means that when they are dissolved in water, they do not dissociate into ions, which is a characteristic of charged molecules.

3. **Dissolving in Water**: When glycerides are dissolved in water, they form a neutral solution. This is because they do not release hydrogen ions (H⁺) or hydroxide ions (OH⁻) into the solution, maintaining a neutral pH.

4. **Hydrogenation**: Glycerides can undergo hydrogenation, which is a chemical reaction where hydrogen is added to unsaturated fats, converting them into saturated fats. Therefore, the statement that they do not undergo hydrogenation is incorrect.

5. **Charge and Ionic Nature**: Glycerides do not carry any charge. This differentiates them from other lipids that may have ionic characteristics. They exist as neutral molecules in solution.

6. **Conclusion**: The correct reason why glycerides are called neutral lipids is that they dissolve in water to give a neutral solution.

**Final Answer**: Glycerides are called neutral lipids because they dissolve in water to give a neutral solution.
