Cell membrane
Comprised of 2 molecules that are lipids (fats) called Phospholipids. Made up of P04. In between the 2 Phosphorous molecules is a Lipid Barrier - the inside of either side is the Fatty Acid Tail
Phosphate Head
Negative charge. Can interact with water. Hydrophilic. P04
Fatty Acid Tails
Hydrophobic.`
Liposoluble
can pass through the membrane
Water soluble
Cannot pass EXCEPT water can
Hypertonic

Hypotonic
