BI 107 ORGANIC CHEMISTRY Dr Potter ORGANIC MOLECULES (Carbon based molecules) (4 major groups) Straight chains, branched chains, rings are common shapes Carbon has 4 valence electrons, very good at forming covalent bonds 4 singles, one double and two singles, two doubles, etc ISOMERS: same chemical formula but different arrangement of those atoms Structural: very different structures Geometric: only with C=C bond (prevents rotation) Enantiomers/stereoisomers: mirror images Minor variations can be biologically significant! HYDROCARBONS – molecules of just carbon and hydrogen (hydrophobic) FUNCTIONAL GROUPS – all polar, increase polarity, increase chemical (therefore biological) diversity. See text. MONOMERS AND POLYMERS Monomers – about 40 different organic building blocks Polymers - 1,000s formed by covalently bonding monomers into “polymers” Three of the four groups have their own unique monomers, polymers CARBOHYDRATES: CH 2 O very hydrophilic Monomers = monosaccharides Hexoses: Glucose, fructose, galactose
