Lipids

(Sara Kamstra)

4 Types of Lipids

What are Lipids

  • Mostly C and H atoms (non- polar)
  • Repels water (hydrophobic)
  • Insoluble in water
  • Very small partial change
  • London forces are in a lipid, weakest inter molecular forces




Types of Lipids (More in Google Doc)

  • Fats
  • Phospholipids
  • Steroids
  • Waxes






Triglycerides

  • Most common type of lipid
  • Formed when the three hydroxide (OH-) groups of a single glycerol molecule react with the carboxylic group (COOH-) of three fatty acids by forming ester bonds
  • Common lengths are 16,18,20
  • Offer energy to cells



Saturated and Unsaturated Fats

  • Saturated fats
  1. Full of Hydrogen molecules
  2. Less reactive
  3. Straight, solid chains
  4. In animals
  5. Not good for you
  • Unsaturated fats
  1. Full of C=C bonds
  2. More reactive
  3. easier to breaks down
  4. They have more space and can bend
  5. Bendable
  6. In plants
  7. Good for you
