Triglycerides are made up of glycerol and three fatty acids.
00:05
They're bonded together by removing a hydroxyl group from one molecule and a hydrogen from the other to get water.
00:12
Is this hydrogen bonding, digestion, hydrolysis or dehydration synthesis? right.
00:21
Hydrogen bonding is a bond between a hydrogen and an electronegative atom on another molecule.
00:28
For example, if you look at water, here is some water, and this is a polar molecule, so this is a little bit negative, but hydrogen is a little bit positive, and you get this bond between these.
00:44
And this is non -covalent, so it's an intermolecular bond, and that's not all looking at here, because in a lipid like triglyceride, they are bonded covalently.
00:56
So it's not hydrant bonding.
00:58
What about digestion? digestion is the breaking down of molecules, into smaller parts.
01:04
And we're not seeing that.
01:05
We're seeing the build -up of complex molecules.
01:08
So is it hydrolysis or dehydration? well, these are interesting because they are opposites of each other.
01:13
Hydrolysis, you add water to break something down...
