In water, position themselves so that the hydrophilic head groups can interact with water molecules while the hydrophobic tails cluster together, away from water molecules. This structure is called a phospholipid bilayer.
Has a hydrophilic hydroxyl group and a hydrophobic rest of the molecule
Can insert into cell membranes, with the hydroxyl group interacting with phospholipid head groups and the hydrophobic part interacting with fatty acid tails
Plays a key role in controlling the fluidity of cell membranes
A phosphoglyceride has two fatty acids attached to one carbon atom on the glycerol backbone and one fatty acid attached to another carbon atom on the same molecule.
The polar head is called the glycerophosphate group, which contains phosphorus.
