In this chapter you will understand: What is lipit? Structural properties of 2 major classes of lipids, know the functions of the major classes of acyl-lipids, know the functions of the major classes of isoprenoids (steroids, carotenoids/chlorophyll, lipid vitamins, ubiquinone/plastoquinone),. | Chapter 9 (part 1) Lipids and Membranes Lipid Subclasses Fatty acids Fatty acid nomenclature Common saturated fatty acids common name IUPAC name melting point (Co) 12:0 laurate dodeconoate 44 14:0 myristate tetradeconoate 52 16:0 palmitate hexadeconoate 63 18:0 stearate octadeconoate 70 20:0 arachidate eicosanoate 75 22:0 behenate docosanoate 81 24:0 lignocerate tetracosanate 84 Common unsaturated fatty acids common name IUPAC name melting point (Co) 16:0 palmitate hexadeconoate 63 16:1 D9 palmitoleate cis-D9-hexadeconoate 18:0 stearate octadeconoate 70 18:1 D9 oleate cis-D9- octadeconoate 13 18:2 D9,12 linoleate cis-D9,12- octadeconoate -9 18:3 D9,12,15 linolenate cis-D9,12,15- octadeconoate -17 20:0 arachidate eicosanoate 75 20:4 D5,8,11,14 arachindonate cis- D5,8,11,14-eicosatetraenoate -49 Physical Properties of Fatty acids 18:0 18:1 18:3 70o 13o -17o Unusual fatty acids can function analogously to unsaturated fatty acids Phospholipids Common membrane phospholipids Enzymes used to Dissect Phospholipid Structure | Chapter 9 (part 1) Lipids and Membranes Lipid Subclasses Fatty acids Fatty acid nomenclature Common saturated fatty acids common name IUPAC name melting point (Co) 12:0 laurate dodeconoate 44 14:0 myristate tetradeconoate 52 16:0 palmitate hexadeconoate 63 18:0 stearate octadeconoate 70 20:0 arachidate eicosanoate 75 22:0 behenate docosanoate 81 24:0 lignocerate tetracosanate 84 Common unsaturated fatty acids common name IUPAC name melting point (Co) 16:0 palmitate hexadeconoate 63 16:1 D9 palmitoleate cis-D9-hexadeconoate 18:0 stearate octadeconoate 70 18:1 D9 oleate cis-D9- octadeconoate 13 18:2 D9,12 linoleate cis-D9,12- octadeconoate -9 18:3 D9,12,15 linolenate cis-D9,12,15- octadeconoate -17 20:0 arachidate eicosanoate 75 20:4 D5,8,11,14 arachindonate cis- D5,8,11,14-eicosatetraenoate -49 Physical Properties of Fatty acids 18:0 18:1 18:3 70o 13o -17o Unusual fatty acids can function analogously to unsaturated fatty acids Phospholipids Common membrane phospholipids Enzymes . | Chapter 9 (part 1) Lipids and Membranes Lipid Subclasses Fatty acids Fatty acid nomenclature Common saturated fatty acids common name IUPAC name melting point (Co) 12:0 laurate dodeconoate 44 14:0 myristate tetradeconoate 52 16:0 palmitate hexadeconoate 63 18:0 stearate octadeconoate 70 20:0 arachidate eicosanoate 75 22:0 behenate docosanoate 81 24:0 lignocerate tetracosanate 84 Common unsaturated fatty acids common name IUPAC name melting point (Co) 16:0 palmitate hexadeconoate 63 16:1 D9 palmitoleate cis-D9-hexadeconoate 18:0 stearate octadeconoate 70 18:1 D9 oleate cis-D9- octadeconoate 13 18:2 D9,12 linoleate cis-D9,12- octadeconoate -9 18:3 D9,12,15 linolenate cis-D9,12,15- octadeconoate -17 20:0 arachidate eicosanoate 75 20:4 D5,8,11,14 arachindonate cis- D5,8,11,14-eicosatetraenoate -49 Physical Properties of Fatty acids 18:0 18:1 18:3 70o 13o -17o Unusual fatty acids can function analogously to unsaturated fatty acids Phospholipids Common membrane phospholipids Enzymes used to Dissect Phospholipid .
