All the following statement describing lipids are ture except:

Options

A. Oxygen content may be more than carbon and hydrogen
B. They are poorly soluble in water
C. They are structural components of membranes
D. They are intracellur energy source

Answer

To solve the question regarding which statement about lipids is incorrect, we will analyze each statement provided about lipids.

### Step-by-Step Solution:

1. **Understanding Lipids**:
- Lipids are a diverse group of hydrophobic organic molecules that include fats, oils, waxes, and steroids. They play critical roles in biological systems, including energy storage, structural components of cell membranes, and signaling.

2. **Analyzing Each Statement**:
- **Statement 1**: "Oxygen content may be more than carbon and hydrogen."
- This statement is incorrect. In lipids, the ratio of carbon (C) to hydrogen (H) is typically 1:2, and oxygen (O) is present in a much smaller amount. Therefore, oxygen content is not more than carbon and hydrogen.

- **Statement 2**: "They are poorly soluble in water."
- This statement is true. Lipids are generally hydrophobic (water-repelling) and are poorly soluble in water, but they dissolve well in organic solvents like benzene and hexane.

- **Statement 3**: "They are structural components of membranes."
- This statement is true. Lipids, particularly phospholipids, are fundamental components of cell membranes, contributing to their structure and function.

- **Statement 4**: "They are intracellular energy sources."
- This statement is also true. Lipids serve as a significant source of energy for cells, stored as fats and used when needed.

3. **Conclusion**:
- After analyzing all the statements, the only incorrect statement is **Statement 1**: "Oxygen content may be more than carbon and hydrogen." Thus, the answer to the question is that the incorrect statement is option 1.

### Final Answer:
The incorrect statement is: **Oxygen content may be more than carbon and hydrogen.**
