  1. lipids
    macromolecules grouped together they are hydrophobic

    mostly hydrocarbons/nonpolar covelant bonds
  2. saturated fat-solid
    • glyerol head
    • 3faty acid tails

    maximum of number of hydrogens attached to each c

    no bend in tails

    higher meltin point tail closer together
  3. unsaturated fat
    • glycerol head
    • 3fatty tails
    • at least one tail has a double covelant bond between c

    tails bent

    low melting temperature
  4. polyunsaturated fat
    fatty tail that has more than one covelant bond between the c
  5. phospholipids-3parts
    • glycerol section
    • fatty acid chain
    • phosphate group
  6. phospholipids
    one end hydrophobic and end is hydrophilic
  7. bilayer
    water added self assemble into a bilayer with hydrophobic tails pointing toward he interior

    • arrangement found in cell membranes
    • major component of all cell membranes
