Most organic compounds are held together by covalent bonds. An example of an organic compound is glucose (C6H12O6), which is shown in Figure 3.12. Glucose is a simple sugar that living cells use for energy. All other compounds are called inorganic compounds. Glucose, like any other carbohydrate, is an organic compound. Recall that organic compounds are those that have carbon atoms bonded to hydrogen (most prevalent linkage), oxygen, and nitrogen atoms. Glucose, as evident by its molecular formula, consists of carbon atoms bonded to hydrogen atoms and oxygen atoms. Therefore, it is in fact an organic compound.
