Which of the following is an incorrect statement regarding Lipids?

Options

A. Lipids are polymers of glycerol and fatty acids
B. Fats have higher melting point as compared to oils
C. Bee wax is an ester of palmitic acid and myricyl alcohol
D. Glycerol is trihydroxy propane

Answer

To determine which statement regarding lipids is incorrect, let's analyze each option step by step:

### Step 1: Analyze Option 1
**Statement:** Lipids are polymers of glycerol and fatty acids.

- **Explanation:** Lipids are indeed composed of glycerol and fatty acids, but they do not form polymers in the traditional sense. Polymers are large molecules made up of repeating units (monomers). While lipids can be made from glycerol and fatty acids, they do not necessarily polymerize in the same way as proteins or nucleic acids. Therefore, this statement is **incorrect**.

### Step 2: Analyze Option 2
**Statement:** Fats have a higher melting point as compared to oils.

- **Explanation:** This statement is correct. Fats are typically saturated fatty acids, which have higher melting points and remain solid at room temperature. Oils, on the other hand, are usually unsaturated and remain liquid at room temperature. Thus, this statement is **correct**.

### Step 3: Analyze Option 3
**Statement:** B-wax is an ester of palmitic acid and myricyl alcohol.

- **Explanation:** This statement is also correct. B-wax is indeed an ester formed from palmitic acid (a fatty acid) and myricyl alcohol (a long-chain alcohol). Therefore, this statement is **correct**.

### Step 4: Analyze Option 4
**Statement:** Glycerol is trihydroxypropane.

- **Explanation:** This statement is correct as well. Glycerol (or glycerin) has three hydroxyl (–OH) groups and three carbon atoms, making it a trihydroxy compound. The term "propane" refers to the three carbon atoms in the structure. Thus, this statement is **correct**.

### Conclusion
After analyzing all the options, the **incorrect statement** regarding lipids is:
- **Option 1:** Lipids are polymers of glycerol and fatty acids.
