More complicated chemical molecules may contain more than one functional group within their structure, which can sometimes affect the chemical reactions they undergo. The names of organic molecules are systematic references to the functional groups within the molecule, and can thus be used to identify these. functional group in chemistry is the part of the molecule that gives it its particular reactivity; simple molecules that contain the same functional group in their structure can be expected to react in similar ways.

All Sugars Are Not the Same. Sucrose and high-fructose corn syrup are major sources of fructose and glucose added to foods. Sucrose -- table sugar -- is equal parts fructose and glucose. HFCS is glucose and fructose mixed in different concentrations, the most common being 55 percent fructose and 45 percent glucose. HFCS is in soft drinks and pastries as well as many processed foods.
