Lipids

Lipids. Fats, Oils, Etc. Made up of…. Carbon Hydrogen Oxygen. Function. Energy Storage and Insulation 9 calories per gram versus 4 calories per gram for carbohydrates. No MONOMER!! (Gasp!). Because the structure of every lipid is so different, we cannot label a “monomer”

Presentation Transcript

  1. Lipids Fats, Oils, Etc.

  2. Made up of… • Carbon • Hydrogen • Oxygen

  3. Function • Energy Storage and Insulation • 9 calories per gram versus 4 calories per gram for carbohydrates

  4. No MONOMER!! (Gasp!) • Because the structure of every lipid is so different, we cannot label a “monomer” • We will discuss the structure of four types of lipids. You will be responsible of knowing the structure AND function of each!

  5. Put together by none other than…. Dehydration synthesis Structure of Fats… • One Glycerol molecule • Three Fatty Acid chains

  6. 1) Fats and Oils ~ Saturated Fats: solids at room temperature contain LOTS of Hydrogen ~Unsaturated Fats: liquids at room temperature contain LESS Hydrogen

  7. 2) Waxes ~ used for waterproofing and insulation ~ ex: bird feathers, ear wax ~ composed of a fatty acid attached to an alcohol

  8. 3) Steroids ~made of Carbon Rings ~ex: Cholesterol, Vitamin D, hormones

  9. 4) Phospholipids ~make up the membranes that surround your cells ~Composed of a glycerol, 2 fatty acid chains, and a phosphate group.

  10. Phospholipid Membrane
