When glucose forms a ring the original aldehyde carbon becomes chiral and is labeled the anomeric carbon, usually designated with a *. The hydroxyl group attached to the new chiral carbon has a 50% chance of being above the plane of the ring or beta and a 50% chance of being below the plane of the ring or alpha.
What is the anomeric carbon in glucose?
When a molecule such as glucose converts to a cyclic form, it generates a new chiral center at C-1. The carbon atom that forms the new chiral center (C-1) is called the anomeric carbon. Anomers are special cases of epimers that differ in position at the anomeric carbon in particular.
Does glucose contain an anomeric carbon?
An equilibrium mixture of glucose contains approximately one-third α anomer, two-thirds β anomer, and <1% of the open-chain form. The same nomenclature applies to the furanose ring form of fructose, except that α and β refer to the hydroxyl groups attached to C-2, the anomeric carbon atom (see Figure 11.5).
