What is ansimer?

Answer 1

Ansimer refers to a type of isomerism where compounds, typically carbohydrates, differ in the configuration at a specific carbon atom, known as the anomeric carbon, which is usually part of a hemiacetal or hemiketal functional group. This form of isomerism is particularly significant in the context of sugars, where it affects their reactivity and biological function. For example, in glucose, the two anomers are alpha (α) and beta (β) based on the orientation of the hydroxyl group at the anomeric carbon.
