Unformatted text preview: Chapter 5 • Check out animated tutorial link in chapter 3 in the following text site: • www.thelifewire.com • Macromolecules are large molecules composed of thousands of covalently connected atoms • Four macromolecules in cells: – Carbohydrates – Proteins – Nucleic acids – Lipids • Only three of the four macromolecules are polymers 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 Need Enzymes!! Need Energy!! 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 What we will cover • Carbohydrates – Types, structures, function • Lipids – Types, structures, functions • Proteins – Amino acids, polypeptides, protein structure and function • Nucleic acids – DNA and RNA CARBOHYDRATES • MONOSACCHARIDES • DISACCHARIDES • POLYSACCHARIDES The structure of glucose – C 6 H 12 O 6 1 2 3 4 5 6 MOLECULAR FORMULA (CH 2 O) n 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 Aldoses (e.g., glucose) have an aldehyde group at one end. Ketoses (e.g., fructose) have a keto group, internal....
