lipids are classified into fat or oil on the basis of their_____.

Answer

To answer the question, "Lipids are classified into fat or oil on the basis of their _____," we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Lipids**:
- Lipids are a diverse group of organic compounds that are generally hydrophobic (insoluble in water) and soluble in non-polar solvents. They include fats, oils, waxes, and steroids.

2. **Types of Lipids**:
- Lipids can be classified into different categories based on their structure and properties. They include fatty acids, triglycerides, phospholipids, and sterols.

3. **Fatty Acids**:
- Fatty acids, which are the building blocks of many lipids, can be saturated (with single bonds between carbon atoms) or unsaturated (with one or more double bonds between carbon atoms).

4. **Classification of Lipids**:
- Lipids can be classified into fats and oils based on their physical properties, particularly their melting points.
- Fats are typically solid at room temperature, while oils are liquid at room temperature.

5. **Melting Point**:
- The melting point is the temperature at which a solid becomes a liquid. Fats generally have higher melting points due to their saturated fatty acid content, while oils have lower melting points due to the presence of unsaturated fatty acids.

6. **Conclusion**:
- Therefore, lipids are classified into fat or oil on the basis of their melting point.

### Final Answer:
Lipids are classified into fat or oil on the basis of their **melting point**.
