Glucose solvation mechanism, illustration. The main bonding in molecular solvation complexes is hydrogen bonding. A glucose molecule (centre) is shown


Glucose solvation mechanism, illustration. The main bonding in molecular solvation complexes is hydrogen bonding. A glucose molecule (centre) is shown surrounded by eight water molecules (H2O), with the hydrogen bonding shown by dotted lines. The atoms are colour-coded: carbon (black), hydrogen (white), and oxygen (red). The glucose molecule has six oxygen atoms, five of which form hydroxyl groups (OH) that form hydrogen bonds with the water molecules. The water molecules surround the partial charges (delta minus and delta plus) on the oxygen and on the hydrogen atoms of the glucose, forming hydrogen bonds: some from the water hydrogen atoms to the glucose oxygen atoms, and others from the hydrogen atoms of the hydroxyl groups to the oxygen atoms of the water. For this diagram without the electrical charges shown, see image C040/4049.
