All right, so we're drawing two peptides.
00:02
The first is a tetrapeptide.
00:04
The second is a heptopeptide.
00:06
So starting for the first one, we should just c -h -e -m, spells out a chem.
00:11
Starting with the n, right? basically just going to draw my backbone to start.
00:37
Okay, so now i can draw my 4.
00:39
Starting with c, that's cysteine, so i'll just draw my cysteine here.
00:45
H is histidine.
00:48
So drawing my five -membered ring with the nitrogen in it.
00:58
E is going to be glutamac acid, so i'm going to draw one, two carbons, and then just a co2h, and then m is going to be methyanine.
01:07
So one, two carbons, and then a thio -methel, i guess, is what you would call that.
01:15
But either way, this is the peptide, c -h -e -m.
01:20
All right, so now i'm doing our heptepet, right? so the pept -i -d -e, which conveniently spells out peptide.
01:28
Start with my nitrogen.
01:32
And then i'm just going to draw out my seven spots.
01:54
So that's one.
02:22
All right, so that should be our backbone.
02:24
So normally i would write this kind of age 3 at the end here...
