C. BIOLOGICAL MOLECULES C1. Synthesis and Hydrolysis of Polymers - most important biological compounds are polymers - Poly means "many" Polymers - a many piece chain of subunits - Subunits are; sugars, amino-acids, nucleotides, or fatty acids. - these are made (synthesized) or broken down (Hydrolysis) over and over in living cells C2. Types of Polymers Proteins : Polymers of amino acids Nucleic acids (DNA, RNA): Polymers of nucleotides Carbohydrates : Polymers of sugars Lipids : Polymers of fatty acids and glycerol C.3 to C.6 Carbohydrates - Empiracle formula (CH20)n - A repeating chain of sugars (saccarides)

- polysaccarides - many saccarides linked together Glucose - a basic sugar (C6 H12 O6) But the molecule has a ring structure This is a mono (one) saccharide - others include fructose, ribose, deoxyribose, etc. Disaccharide - two sugars joined together Examples of disaccharides : - maltose (two glucoses) - sucrose (a glucose and fructose) - lactose (galactose and glucose) To break the bond between two sugars, a H2O is added back (Hydrolysis) The Main Functions of Carbohydrates are: Energy: Bonds between Carbon atoms can be broken, the Hydrogen atoms stripped off and the energy released can be used by cells
