In problem 52, we need to draw the two enantiomers of the protein or the amino acid, cysteine.
00:13
Cistine is our molecule and anantiumers.
00:26
Our molecules of, they're different isomers of the same molecule that are mirror images, but are non -superimposable.
01:00
All right.
01:00
Now let's look at cysteine.
01:04
So for cysteine, the r.
01:08
The r group or the side chain is going to be ch2 as sh.
01:20
So let's draw one an antiumer.
01:24
Let's have our central, our chiral carbon.
01:28
We'll draw the hydrogen and the amid in the plane of the page...
