Glucose is one of smallest units of carbohydrates and the primary energy source for your body. Every carbohydrate in your diet is digested and broken down to this simple sugar, which your body can easily burn for energy. Like many of the molecules in your body, glucose is an organic molecule.
One way to determine if a molecule is organic or inorganic is to look at its molecular formula. With some rare exceptions, organic molecules contain carbon atoms that are typically linked to hydrogen, oxygen or nitrogen atoms. Glucose contains six carbon atoms, 12 hydrogen atoms and six oxygen atoms, which makes it and any other carbohydrate an organic compound.
