Macromolecules - Carbohydrates, lipids, proteins, nucleic acids Much of the organic matter of cells is found in the form of macromolecules, which are usually polymers formed by covalent bonding of many repeating monomers - When two monomers are joined together, the reaction usually involves the elimination of a hydrogen atom from one monomer and a hydroxy group from the other; this is called dehydration synthesis (Tortora et al., Figure 2.9) and results in formation of a molecule of water. - In the reverse reaction, hydrolysis, atoms from a molecule of water are incorporated as the covalent bond joining the monomers is broken The carbohydrates (general formula (CH 2 O) n ) are a diverse group of organic compounds that includes the sugars and starches. - Carbohydrates perform a number of functions in living cells, but are especially important as components of structural elements (e.g., cell walls) and as energy storage compounds. - The simplest carbohydrates are the
