Lipids

Cards (6)

  • Triglycerides are composed of 1 glycerol and 3 fatty acids
  • Saturated fatty acids have no double bonds, but unsaturated fatty acids have kinks in their chains.
  • Fats are saturated and act as short term energy stores, but oils are unsaturated and act as long term energy stores.
  • Phospholipids are the main components of the cell membrane and consist of one glycerol, two fatty acids and one phosphate group.
  • Steroids include cholesterol which is an essential component of the cell membrane and the sex hormones.
  • Steroids differ from other lipids because their skeletons have four fused carbon rings. However, they are classified as lipids because of their hydrophobic nature.
