Unformatted text preview: CELL COMPONENTS Use chemistry to connect structure with function ! Lipids (membranes) ! Carbohydrates (cell wall) ! Proteins (membranes, enzymes, chromatin, microtubules, microfilaments) ! Nucleic acid (chromatin, ribosomes) Note "functional groups" of biochemicals (Sadava et al. [8th edn], Fig. 3.1) LIPIDS (FATS, OILS) Carbon chain C has 4 outer shell electrons, makes 4 covalent bonds (shared e- pairs) If the 4 bonds are to four different atoms (saturated), they are equally spaced around atom (tetrahedral) Tetrahedral arrangement means that C-C chain is zig-zag Cs bond to Cs, Hs (one bond per H) C C C C C C \ / \ / \ / \ / \ / \ C C C C LIPIDS (FATS, OILS) Carbon chain C has 4 outer shell electrons, makes 4 covalent bonds (shared e- pairs) If the 4 bonds are to four different atoms (saturated), they are equally spaced around atom (tetrahedral) Tetrahedral arrangement means that C-C chain is zig-zag Cs bond to Cs, Hs (one bond per H) C C C C C C \ / \ / \ / \ / \ / \ C C C C...
