Document Summary
Allows us to build large and complicated molecules. Hydrocarbons: molecules only containing hydrogen and carbon can also form extremely stable molecules with double bonds. Groups where two molecules will differ by only one or a few atoms and their location. Eating -> breaks bonds between energy, giving us energy. We store this energy by building new bonds in a new molecule called atp (adenosine. Adp + p -> atp requires energy. Atp -> adp + p releases energy. Monomer - single unit of a molecule. Breaking down polymers into monomers done by hydrolysis reaction. Each molecule is organic - containing carbon and hydrogen. Body can break down other biomolecules and make glucose. 3 fates - converted to energy, linked to form glycogen, stored as fat: fructose. 2 monosaccharide - disaccharide two monosaccharides are bonded by glycosidic bonds. Polymer - polysaccharide: sucrose, lactose, cellulose, glycogen, starch complex polysaccharides - starches.
