  • Lipids
    • Lipids
      • Made of carbon, hydrogen and oxygen
      • They are insoluble in water
      • Function of lipids
        • Energy storage
        • Making biological membranes
        • Insulation
        • Protection of organs
        • Boyancy
        • Acting as hormones
      • They are made from Fatty acids and Glycerol
    • Fatty Acids
      • Contain a Acid Group
        • Normally donated as 'R'
      • Could be saturated or unsaturated
        • Saturated = no double bonds
        • unsaturated contains double bonds
      • Animals tend to have more saturated, solid at room temperature
        • Plants = Unsaturated and more oily
    • Triglycerides
      • One glycerol and 3 fatty acid molecules.
      • Bonds between molecules are called ester bonds
        • Formed-during a condensation reaction
      • Triglycerides are hydroponic and insoluble in water
    • Phospholipids
      • Consist if a Glycerol backbone
      • Fatty acid talls, however third tail has been replaced by a phosphate
      • Phosphate-head = hydrophilic
        • Phosphate tail = hydrophobic
      • Phosphates can have saturated or unsaturated fatty acids, allows for control of the fluidity of the membrane.
