Lipids have a molecular mass of :

Options

A. Less than 800 daltons
B. 800-200 daltons
C. 2000-5000 daltons
D. greater than 10,000 daltons

Answer

### Step-by-Step Solution:

1. **Understanding Lipids**:
- Lipids are macromolecules that include hydrocarbons. They are essential biological molecules that play various roles in living organisms.

2. **Examples of Lipids**:
- Common examples of lipids include fats, waxes, oils, and sterols. These substances are crucial for energy storage and structural functions in cells.

3. **Functions of Lipids**:
- Lipids help in storing energy and are key components of cell membranes. They form structures like phospholipids, which are critical for the integrity and functionality of cell membranes.

4. **Molecular Mass of Lipids**:
- The molecular mass of lipids is generally less than 800 Daltons. This is a significant characteristic that helps differentiate them from other macromolecules.

5. **Understanding Dalton**:
- Dalton (Da) is a unit of mass used to express atomic and molecular weights. One Dalton is defined as 1/12th the mass of a carbon-12 atom.

6. **Conclusion**:
- Based on the information gathered, the correct answer to the question regarding the molecular mass of lipids is that it is less than 800 Daltons.

### Final Answer:
Lipids have a molecular mass of less than 800 Daltons.
