Is Glucose a Hydrogen Bond?

When glucose mole fraction is 0.003, all glucose molecules are hydrogen bonded with water molecules and there is no intermolecular hydrogen bonds between glucose molecules which is consistent with density profiles of glucose and water molecules in Fig.

Does glucose have hydrogen bonds?

Remembering our definition of hydrogen bond donors and acceptors, you can see that glucose has 5 hydrogen bond donors (H-O) and 6 hydrogen bond acceptors (O). Water molecules can form hydrogen bonds at each of these sites and solvate the glucose molecule. So, it cannot form hydrogen bonds to water.

What type of bond does glucose make?

The carbon atoms in the glucose ring each have four covalent bonds. The best, or optimum angle, between all these bonds is 109.5o, which results in a perfect tetrahedron.

Hydrogen bonding is a special type of dipole-dipole attraction between molecules, not a covalent bond to a hydrogen atom. It results from the attractive force between a hydrogen atom covalently bonded to a very electronegative atom such as a N, O, or F atom and another very electronegative atom.
