Document Summary
Carbs, proteins and nucleic acids are polymers: lipids aren"t. Monomers make up polymers and joined by covalent bonds. Monomers bonded in dehydration synthesis (lose h20: one monomer provides hydroxyl (oh-) and other provides h. Hydrolysis disassembles monomers by adding h2o again. Enzymes speed up reactions by helping break down large polymers eg. in digestion: released monomers bloodstream cells dehydration reaction to make new polymers for specific functions. Monosaccharides disaccharides polysaccharides: monosaccharides combo of ch2o (glucose for example, disaccharides joined by a glycosidic linkage, glucose + glucose maltose, glucose + fructose sucrose (table sugar, glucose + galactose lactose. Trademarks of a sugar: carbonyl (co) group and multiple hydroxyl (oh-) Plants store starch, polymer glucose molecules, as granules in plastids: plants can stock surplus glucose. Animals store glycogen in liver and muscle cells: cannot sustain us for very long, about a day of energy for a human stored.
