The lipid component of cell membrane mainly consists of

Options

A. Glycerides
B. Phosphoglycerides
C. Oligosaccharides
D. Proteins

Answer

To answer the question regarding the lipid component of the cell membrane, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding the Cell Membrane Composition**:
- The cell membrane is primarily composed of two main types of molecules: lipids and proteins.

2. **Identifying the Lipid Component**:
- The question specifically asks about the lipid component of the cell membrane.

3. **Analyzing the Options**:
- The options provided are:
- Glyceride
- Phosphoglycerides
- Oligosaccharides
- Proteins

4. **Determining the Correct Lipid Type**:
- Among these options, phosphoglycerides (also known as phospholipids) are the primary type of lipids found in the cell membrane.
- Phosphoglycerides consist of a glycerol backbone, two fatty acid tails, and a phosphate group, which gives them both hydrophilic (water-attracting) and hydrophobic (water-repelling) properties.

5. **Understanding the Structure**:
- The structure of phosphoglycerides allows them to form a bilayer in the cell membrane, with the hydrophilic heads facing outward towards the aqueous environment and the hydrophobic tails facing inward, away from water.

6. **Conclusion**:
- Therefore, the lipid component of the cell membrane mainly consists of phosphoglycerides.

### Final Answer:
The lipid component of the cell membrane mainly consists of **phosphoglycerides**.
