From strongest to weakest, i've labeled the types of intramolecular react or coordinations we can have.
00:08
So ionic hydrogen bonding, dipole, dipole, then lend in dispersion as the weakest.
00:14
So at site a, these are both just alkyl chains.
00:18
There aren't any dipole moments within that compound or within either of those sites of the amino acids.
00:24
Therefore, it only has london dispersion.
00:27
At b, this carbonyl has a dipole moment.
00:32
So does the nitrogen.
00:33
So it at least has dipole, dipole.
00:35
All interactions are going to have lend in dispersion forces.
00:39
But there's also hydrogen bonding because we have the nitrogen hydrogen, hydrogen is a hydrogen bond, as well as an oxygen, hydrogen, hydrogen bond.
00:47
So that's the main bond they're pointing to here.
00:50
At site c, we have an ionic interaction because we have a full positive and a full negative charge here...
