Unformatted text preview: Cells have a structural hierarchy Chapter 5 • Four macromolecules in cells: – Carbohydrates – Proteins – Nucleic acids – Lipids Synthesis of Polymers • Condensation (Dehydration) reactions HO H 1 2 3 HO HO H 1 2 3 4 H H 2 O Short polymer Unlinked monomer Longer polymer Dehydration removes a water molecule, forming a new bond Figure 5.2A Breakdown of polymers • Hydrolysis HO 1 2 3 H HO H 1 2 3 4 H 2 O H HO Hydrolysis adds a water molecule, breaking a bond Figure 5.2B Covalent bonds connecting monomers • Carbohydrates • Glycosidic bond • Proteins • Peptide bond • Nucleic acids • Phosphodiester bond CARBOHYDRATES • MONOSACCHARIDES • DISACCHARIDES • POLYSACCHARIDES Fig. 5-3a A l d o s e s Glyceraldehyde Ribose Glucose Galactose Hexoses (C 6 H 12 O 6 ) Pentoses (C 5 H 10 O 5 ) Trioses (C 3 H 6 O 3 ) MONOSACCHARIDES… Fig. 5-3b K e t o s e s Dihydroxyacetone Ribulose Fructose Hexoses (C 6 H 12 O 6 ) Pentoses (C 5 H 10 O 5 ) Trioses (C 3 H 6 O 3 ) Monosaccharides Variations based on: A) No. of Carbons in the carbon skeleton B) Location of Carbonyl group C) Spatial arrangement of atoms eg. varying configurations of OH groups Heptoses – 7 carbon Hexoses – 6 carbon Pentoses – 5 carbon Tetroses – 4 carbon Trioses – 3 carbon A) No. of carbons in the C skeleton A) No. of carbons in the C skeleton B) Location of carbonyl group...
