Amphopathic lipids are a special type of lipid that contains both a hydrophilic region, which means, you can get this from the root word, water and philic, which means water -loving.
00:19
So these are the parts that are attracted to water and want to bind with it because of the opposite dipoles.
00:26
And then it also includes hydrophobic, so fear of water.
00:31
These are the parts that don't want to be near water at all.
00:35
So ampopathic has both hydrophobic and hydrophobic regions.
00:40
And a really easy example of this in nature is a cell membrane.
00:45
So i'm going to draw a bi -layer real quick.
00:49
A lot of cell membranes are bi -layers, so that means they have two sets of lipids stacked on top of each other.
00:55
And that prevents things from getting inside and out of the cell that aren't wanted by the cell.
01:01
So this is the outside, and then this is the inside of the cell...
