Presentation Transcript

  1. What is the function of lipids?

  2. Lipids Uses: • Long Term Energy Storage • LIPIDS ARE BEST AT ENERGY STORAGE • Chemical messengers • Water-proofing • Structure • Cell membranes

  3. Structure • Elements in Lipids • C, H and a little bit of O • Usually long chains of carbon and hydrogen with two oxygens on the end • These long chains are generally called fatty acids

  4. Saturated v. Unsaturated Fatty Acids • Saturated Fatty acids have all single bonds • Unsaturated Fatty acids have at least one double bond. They are BENT.

  5. Form at Room Temperature • Saturated Fatty Acids are solid at room temperature • Unsaturated are liquid

  6. Checkpoint Question • Do you think saturated or unsaturated fatty acids cause more health problems? • Why?

  7. LIPIDS ARE NOT POLYMERS • Lipids ARE NOT POLYMERS • Lipids are just grouped together because: • They are all non-polar • They are all hydrophobic (hate water/can’t dissolve in water)

  8. Types: • Triglycerides • Steroids • Wax • Phospholipids

  9. Triglycerides • One glycerol + three fatty acids

  10. Steroids • Four fused rings

  11. Waxes • A long chain alcohol linked to a long chain fatty acid

  12. Phospholipid • Found in membranes • Glycerol + 1 phosphate group + 2 fatty acids

  13. Checkpoint: How is the structure of lipids related to their function in energy storage?
