Presentation Transcript

  1. Lipids

  2. Lipid Structure • Fats, Oils, Waxes • Energy for cells, cell structure, insulation • 3 Fatty acid molecules bonded w/ glycerol

  3. Lipid Structure • Fats, Oils, Waxes • Energy for cells, cell structure, insulation • Lipids & Proteins compose the cell membrane • Cholesterol: gives cell membrane flexibility • Stucture (2 parts): • “Head” of glycerol • “Tail” of fatty acids molecules • Monomer: Fatty Acid • Polymer: Lipid 3 1 2

  4. How do they bond? • Dehydration synthesis between the glycerol and fatty acids

  5. Saturated Fats • Long chain of C-C single bonds • Each C is “saturated” with H atoms • Solid at room temps • Very common in animal fats

  6. Unsaturated Fats • Long chain of C atoms(some double bonds) • Unsaturated: Less space for H atoms • Liquid at room temps • Plants fats

  7. Which has more H? 18 16
