In the following which is not glyceride

Options

A. Fats
B. Oils
C. Phospholipids
D. Soaps

Explanation

To determine which option is not a glyceride, we first need to understand what a glyceride is.

### Step-by-Step Solution:

1. **Definition of Glyceride**:
- Glycerides are esters formed from glycerol and fatty acids. They can be classified into mono-, di-, and triglycerides based on the number of fatty acid chains attached to the glycerol molecule.

2. **Components of Glycerides**:
- Glycerol: A three-carbon alcohol that serves as the backbone for glycerides.
- Fatty Acids: Long hydrocarbon chains that can be saturated or unsaturated.

3. **Types of Glycerides**:
- **Monoglycerides**: Contain one fatty acid attached to glycerol.
- **Diglycerides**: Contain two fatty acids attached to glycerol.
- **Triglycerides**: Contain three fatty acids attached to glycerol.

4. **Identifying Non-Glyceride**:
- To identify which option is not a glyceride, we need to look for substances that do not fit the definition of being an ester of glycerol and fatty acids.
- Common examples of glycerides include fats and oils (which are triglycerides) and phospholipids (which may contain glycerol but also have phosphate groups).

5. **Examine the Options**:
- If one of the options is soap, we note that soap is typically a sodium salt of fatty acids and does not contain glycerol as part of its structure. Therefore, soap is not classified as a glyceride.

6. **Conclusion**:
- Based on the analysis, the option that is not a glyceride is **soap**.

### Final Answer:
The substance that is not a glyceride is **soap**.
