This question asks us to draw two lewis structures for the dye peptide alanine isolucine and show the resonance structure for the amid linkage.
00:21
So two structures because there are two resonant structures for the amid linkage.
00:26
So we'll start off just by drawing it normally.
00:28
So i've drawn alineine and isolucine in the screen as reference points.
00:32
So if we're drawing a lewis structure here, we'll have, we'll start with the amine on one side.
00:38
This is alanine.
00:40
This is the central carbon of aleneene that has a hydrogen on it.
00:43
And then the r group, which is a methyl group here.
00:48
And then the carboxylic acid.
00:51
But instead when we're joining peptides or amino acids together, we take away this oh -h here from the carbosylac acid and replace it with the amine of the next amino acids.
01:03
This goes right into the end, which has 1h left over...
