Chapter 3 Chemical Building Blocks of Life 3.1 Carbon Chemistry of carbon Functional groups: Hydroxyl Carbonyl Carboxyl Amino Sufhydryl Phosphate Methyl 6 elements make up macromolecules C is central to macromolecules because of its chemistry Monomers Polymers Macromolecule Dehydration Hydrolysis 3.2 Carbohydrates Major fuel molecule Formula (CH2O)N Very versatile Monosaccharide Disaccharides Oligosaccharides Polysaccharides glycogen. starch chitin cellulose 3.3 Nucleic Acids Two main types: DNA and RNA Function also as energy molecules and electron carriers Nucleotides have three parts: Phosphate group Nitrogenous base Pentose sugar DNA Double helix Carries genetic code RNA Single stranded Working nucleic acid mRNA tRNA rRNA Central Dogma of Biology DNARNAproteins 3.4 Proteins Function as work force of the cell Enzymes Defense Transport Support Motion Regulation storage (NH3 – C (H, R) – COOH) 4 levels of structure: Primary Secondary Tertiary Quaternary Motif Domains Chaperone proteins Denaturation 3. 5 Lipids Oils, waxes, fats Non-polar hydrophobic group Functional group is hydrocarbon chains Can be saturated or unsaturated Varied functions Phospholipids
