Which of these have a branched side chain? balin, lucine, methyne, isolucine, lucine, alenine, isolucine, proline, lucine, lysine, valiene, isolucine, lusine, lusine, vailin.
00:17
Okay, when it comes to amino acids, i absolutely recommend flashcards, if you're expected to other structures, but i'll go through the structures of each of these.
00:26
So, first of all, uh, valine.
00:29
So, for all of these, i'm going to start with a...
00:33
The standard structure, and then i'm going to draw each side chain on.
00:50
So this is the standard structure.
00:52
First of all, dalyne.
00:54
So it comes out like this to a carbon, and then two methyl groups.
01:03
So you can see, branched, because it comes to a carbon and then it splits into.
01:07
So that one is definitely branched.
01:11
Okay.
01:13
Lusine.
01:14
So, lusine, i'll just draw the skeleton.
01:18
There's another carbon here.
01:18
Another carbon here and branching.
01:21
So a lot like valine except with an extra ch2 in the middle.
01:25
And but again, definitely branched.
01:29
So baline and lucine are, methionine.
01:33
Methyane looks like this.
01:35
So you have a carbon, another carbon, then a sulphur, and then a methyl group at the end...
