What do you mean by an anomeric carbon? I want an answer preferably for anomeric carbon in carbohydrates (sugars)

Jul 22, 2015

In the cyclic form of a sugar, the anomeric carbon is the carbon that was part of the carbonyl group in the straight-chain structure.

For example, the linear structure of glucose is

When the chain converts to a ring, C-1 becomes a chiral centre.

C-1 is the anomeric carbon.

In D-fructose, the carbonyl group is at $\text{C-2}$.

Here, $\text{C-2}$ is the anomeric carbon.
