Lecture 42
Sterols
- Isoprenoids
o Lipids made up of 5- units like isoprene
o Cholestrol
▪ Components of the membrane
▪ Precursor of estrogen and testrosterone
▪ Almost entirely hydrophobic therefore it
cannot form a bilayer by itself
o Vitamins
▪ A, D, E, K
Lipid Bilayer
- Are able to form biological membranes
- 2D array of amphipathic molecules
o Nonpolar tails associated away from aqueous
interface
o Polar head groups face to aqueous environment
- Forms spontaneously hydrophobic effect
- Very stable
