Figure 2 : Structural diversity of glycan.

a. A chiral center can be interpreted as “0” and “1”.
b. A six-carbon monosaccharide, hexose, consisting of five chiral centers that make all the hexoses, which can be described by the combinations of “0” and “1”.
c. Hexoses can hold a substituting group at each carbon atom.
d. Monosaccharides can be interconnected through an acetal linkage called glycosidic linkage. Glycan can form branched structures as well.
