The correct Answer is:
To solve the question regarding carbohydrates that differ in configuration at the glycosidic carbon (C1 in aldoses and C2 in ketoses), we will follow these steps: ### Step-by-Step Solution: 1. **Understand the Terms**: - **Aldose**: A type of carbohydrate (sugar) that contains an aldehyde group. - **Ketose**: A type of carbohydrate that contains a ketone group. - **Glycosidic Carbon**: The carbon atom involved in the formation of a glycosidic bond, which connects two monosaccharides. 2. **Identify the Relevant Carbons**: - In aldoses, the glycosidic carbon is C1. - In ketoses, the glycosidic carbon is C2. 3. **Define the Types of Isomers**: - **Anomers**: Carbohydrates that differ in configuration at the anomeric carbon (the carbon that becomes a new chiral center during the formation of a glycosidic bond). - **Epimers**: Carbohydrates that differ in configuration at any one specific asymmetric carbon atom, but not at the anomeric carbon. - **Diastereomers**: Stereoisomers that are not mirror images of each other. - **Enantiomers**: Stereoisomers that are mirror images of each other. 4. **Analyze the Question**: - The question specifically asks about carbohydrates that differ in configuration at the glycosidic carbon (C1 for aldoses and C2 for ketoses). This aligns with the definition of anomers. 5. **Conclusion**: - Therefore, carbohydrates that differ in configuration at the glycosidic carbon are called **anomers**. ### Final Answer: The carbohydrates which differ in configuration at the glycosidic carbon (C1 in aldoses and C2 in ketoses) are called **anomers**. ---
