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 about the right end of the polysaccharide chain in glycogen, we can follow these steps:

### Step-by-Step Solution:

1. **Understanding Glycogen Structure**:
- Glycogen is a polysaccharide made up of glucose units linked together by glycosidic bonds. It has a branched structure.

2. **Identifying the Ends of the Polysaccharide Chain**:
- In polysaccharides, there are two ends: one end has a free anomeric carbon (C1) and the other end is where the last glucose unit is attached via a glycosidic bond.

3. **Determining the Right End**:
- The right end of the glycogen chain is where the last glucose unit is attached, and it is important to note whether this end has a glycosidic bond or not.

4. **Recognizing the Reducing and Non-reducing Ends**:
- The end of the polysaccharide chain that has a free anomeric carbon (C1) is known as the reducing end. This is because it can participate in redox reactions.
- The other end, which is involved in a glycosidic bond, is referred to as the non-reducing end.

5. **Conclusion**:
- In glycogen, the right end of the polysaccharide chain is called the **reducing end** because it has a free anomeric carbon and does not have a glycosidic bond.

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