Carbohydrates and Lipids Which of the following statement is true ?

Options

A. Epimers are also anomers
B. Anomers are also epimers.
C. Both of the above statements are true.
D. Neither of the two statement is true.

Explanation

To determine which statement is true regarding epimers and anomers, we need to analyze the definitions and relationships between these two types of carbohydrates.

### Step-by-Step Solution:

1. **Understanding Epimers**:
- Epimers are a type of diastereomer that differ in configuration at only one specific chiral carbon atom. For example, glucose and mannose are epimers because they differ at the second carbon (C2).

2. **Understanding Anomers**:
- Anomers are a special type of carbohydrate isomer that differ in configuration at the anomeric carbon (the carbon derived from the carbonyl group during the formation of a cyclic structure). For example, in glucose, the anomers are alpha (α) and beta (β) forms, which differ at the first carbon (C1).

3. **Analyzing the Statements**:
- **Statement 1**: "Epimers are also Anomers."
- This is false. While both epimers and anomers are types of diastereomers, they refer to different types of differences in structure. Epimers differ at any one chiral center, while anomers specifically differ at the anomeric carbon.
- **Statement 2**: "Anomers are also Epimers."
- This is true. Anomers are a specific case of epimers because they differ at the anomeric carbon, which is one of the chiral centers.

4. **Conclusion**:
- Since only Statement 2 is true, the correct answer to the question is option 2: "Anomers are also Epimers."

### Final Answer:
The correct statement is: **2. Anomers are also Epimers.**
