In majority of the proteins linear polypeptide chain gets coiled in manner form secondary structure

Options

A. Clockwise
B. Anti clockwise
C. Randomly
D. None of the above

Answer

To solve the question regarding the formation of the secondary structure of proteins, let's break it down step by step.

### Step-by-Step Solution:

1. **Understanding Proteins**:
- Proteins are polymers made up of amino acids. They have various levels of structure: primary, secondary, tertiary, and quaternary.

2. **Identifying the Structures**:
- The primary structure refers to the linear sequence of amino acids.
- The secondary structure involves the folding or coiling of this linear chain into specific shapes, primarily alpha-helices and beta-pleated sheets.

3. **Formation of Secondary Structure**:
- The secondary structure is formed due to hydrogen bonding between the backbone atoms in the polypeptide chain. This leads to coiling or folding.

4. **Direction of Coiling**:
- In the majority of proteins, the coiling of the linear polypeptide chain occurs in a clockwise manner. This is particularly true for the formation of alpha-helices.

5. **Conclusion**:
- Therefore, the correct answer to the question is that the linear polypeptide chain gets coiled in a clockwise manner to form the secondary structure.

### Final Answer:
The correct option is **clockwise**.
