In glycogen, the right end of the polysaccharide chain is called

Options

A. Non - reducing end
B. C - terminal
C. Reducing end
D. N - terminal

Answer

To solve the question regarding the right end of the polysaccharide chain in glycogen, follow these steps:

### Step-by-Step Solution:

1. **Understand the Structure of Glycogen**:
- Glycogen is a polysaccharide made up of glucose units linked together. It has a branched structure.

2. **Identify the Ends of the Polysaccharide Chain**:
- In any polysaccharide, there are two distinct ends: the reducing end and the non-reducing end.
- The reducing end is where the free anomeric carbon is located, which can participate in redox reactions.

3. **Determine the Right End**:
- According to the question, we need to identify what the right end of the glycogen chain is called.
- The right end of the polysaccharide chain is referred to as the reducing end.

4. **Clarify the Terminology**:
- The left end of the polysaccharide chain is known as the non-reducing end. This end does not have a free anomeric carbon and cannot act as a reducing agent.

5. **Evaluate the Options**:
- The options provided are:
- A) Non-reducing end
- B) Reducing end
- C) C-terminal
- D) N-terminal
- Based on our understanding, the right end of the glycogen chain is indeed the reducing end.

6. **Select the Correct Answer**:
- Therefore, the correct answer to the question is option B) Reducing end.

### Final Answer:
The right end of the polysaccharide chain in glycogen is called the **reducing end**.
