Phospholipids

• What are phospholipids composed of?

  Glycerol, 2 fatty acids, and a phosphate group.
• Describe how the structure of phospholipids relates to their function?

  Function- cell membrane

  structure- hydrophilic head points outwards, hydrophobic tails point inwards to form a bilayer
• Where are the ester bonds in phospholipids?

  between the phosphate group and glycerol (phospho-ester)

  glycerol molecule and fatty acids
• Give 3 similarities and 2 differences between phospholipids and triglycerides?

  similarities: Both contain glycerol, both contain fatty acids/ester bonds, both made up of C,H,O

  differences: 2 fatty acids vs 3 fatty acids, phospholipids have a phosphate group
