Chapter 3- The Chemical Basis of Life II – Organic Molecules I) Carbon (C HNOPS) a. “6,6,6” 6p+, 6e-, 6n b. C loves H! Hydrocarbons c. C loves C d. Carbon can form long chains e. Chains can branch f. Can form rings Bottom line: there are A LOT of organic molecules II) CHOPNS : Attached to a) Functional groups Def: groups of atoms that recur

b) R-OH hydroxyl group c) Amino group d) Carboxyl group e) Phosphate group f) Sulfhydryl group Others- see table 3.1 III) Facts: 1) All 4 composed of subunits called monomers 2) Synthesis 3) Breakdown 4) 1,3,4. – polymers 2- not polymers

IV)Carbohydrates a) 1C:2H:1O b) B.B.’s= monosaccharides/single sugars/simple sugars c) Loosely categorized - #C atoms Trioses (3) … tetroses(4) … pentoses(5)(DNA/RNA)… hexoses(6)(Glucose) d) Lots of isomers exist. (See fig 3.5) Ex: C 6 H 12 O 6 HOWEVER, Glucose most abundant and important e) Synthesis f) Disaccharides – many exist Ex: sucrose – Glucose and Fructose g) Polysaccharides – 4 main ones (all are polymers of glucose)
