Isomers and Stereoisomers

Anomers:

  • When a molecule such as glucose converts to a cyclic form, it generates a new chiral centre at C-1.
  • The carbon atom that generates the new chiral centre (C-1) is called the anomeric carbon.
  • Anomers are the epimers that differ in configuration only at the anomeric carbon.
  • For example, α-D-glucose and β-D-glucose are anomers.
  • The α form has the anomeric -OH group at C-1 on the opposite side of the ring from the CH2OH group at C-5. The β form has the anomeric -OH group on the same side as the CH2OH group.
