Anomers
Anomers are stereoisomers of cyclized monosaccharide molecules differing only in the configuration of the newly created center of chirality arising from the cyclization (Figure 9.14).

The carbon of a newly created center of chirality arising from the cyclization of a sugar is called an anomeric carbon.

Anomerization occurs to the ribose sugar moiety during de novo purine nucleotide biosynthesis.
