👉 In organic chemistry, an epimer is a molecule that has one or more identical structures (epimers) but different chemical properties. These differences are caused by differing substituents on the carbon atoms in the ring system of the compound. The difference between the two epimers can be due to differences in the presence of oxygen, nitrogen, or sulfur groups, as well as through other chemical modifications.
Epimeres can be classified into two main types based on their molecular formula:
