lipids

• what are the main elements that make up lipids


  carbon hydrogen and oxygen
• what is the difference between carobohydrates and lipids in terms of main elements


  lipids contain less oxygen
• What are triglycerides?


  fats and oils
• what are the main components of triglycerides


  glycerol and 3 fatty acids
• are triglycerides polymers why? / why not?


  no because they are made up of two different types of sub unit
• what is the definition of polymer


  a chain of identical units
• what is the reaction that bonds the fatty acids to the glycerol called


  a condensation reaction
• what type of bond is formed in the condensation reaction between a glycerol and three fatty acids


  ester bonds
• what is a bi product of a condensation reaction


  a water molecules
• what does a fatty acid look like

  
• what does a glycerol look like

  
• What does a triglyceride look like

  
• what are the two types of fatty acids


  saturated and unsaturated
• what is the difference between a saturated fatty acid and a saturated fatty acid


  saturated are single bonds that allow the maximum amount of hydrogen to be bonded where as unsaturated are double bonds that don't bond the maximum amount of hydrogen
• what are the three groups in a saturated fatty acid

  a carboxyl group a hydrocarbon chain and a methyl group
• where are unsaturated fatty acids found


  plant oils
• What are saturated fats?

  the deterioration of the walls of arteries
• what is a aneurysm


  a bulge in a blood vessel
• what are waxes


  Super long fatty acid and alcohol group joined together
• what are the properties of waxes


  insoluble and reduce transpiration on the leafs
• What are phospholipids?


  a triglyceride but with a phosphate group instead of one of the fatty acids
