Hexoses

The objective of this article is to illustrate and visualize the structures and concepts related to the structures of glucose (aldohexose) and fructose (ketohexose).

Figure: Fischer Projection Structure of D-Glucose.

The figure to the left contains glucose drawn as a Fischer projection structure. The most oxidized group, in this case the aldehyde group, is is drawn at the top, all horizontal bonds project to the front of the plane of the screen and all vertical bonds are assumed to project behind the plane of the screen. As shown in the scene below if glucose is set in the Fischer projection conformation carbon #6 (green) circles around to meet carbon #1 (orange).
