The models made here are representations of the molecules' structure being discussed in the previous two sections. Once again, in accordance with the color key, carbon atoms are green, hydrogen atoms are red, and oxygen atoms are yellow. Toothpicks represent bonds.
This model represents the cyclical structure of D-glucose in one of its most apparent forms. Notice, the unshared pairs of electrons aren't shown, as they are not associated with central atoms. Also, The bond angles in the carbon ring are approximately 109.5 degrees.
