The Structure and Function of Glucose
Glucose, also known as dextrose, has a simple and powerful structure. It is a placebo by mouth, but able to stimulate production of repair proteins within minutes of injection in high concentration (click here for more information).
Glucose is a "simple" sugar, called a monosaccharide. The chemical formula is "C6H12O6." It is an example of a 6-carbon ("hexose") sugar.
The 6 carbon atoms (dark grey in the diagram below) form the backbone of the molecule. The oxygen atoms are colored red. The hydrogen atoms (white) are either attached directly to the carbons, or via oxygen as "OH" groups.
The inner ring itself is 6-sided, but only 5 of its corners are made up by carbon atoms. The 6th carbon atom, located outside the ring, has 2 single hydrogens and an OH group. The glucose molecule can form into other configurations, but this structure (called "α-D-glucopyranose") is the most stable and therefore most common in biological systems.
