You may have heard the term phospholipid bilayer when talking about a cell membrane.
00:05
But what exactly is a phospholipid, first of all? and then second, why is it so good at forming cell membranes? so first, i illustrate what exactly a phospholipid is.
00:16
It is a fat molecule, hence lipid.
00:21
It has two tails and a head.
00:24
And the head is hydrophilic.
00:27
So i'm going to draw in blue.
00:30
And then hydrophilic means water -loving.
00:31
So this is polar and it's attracted to bonding with water.
00:35
So if we have another water molecule over here, this, these are going to want to interact.
00:45
And then the tails are hydrophobic...
