So the question asks you to analyze the structure of 20 common amino acid, apart from cho, which elements availability is most critical for protein synthetis? so on the screen, i want to show you the common structure of all amino acid.
00:16
So it doesn't matter which amino acid, they all have something in common.
00:20
It has a central carbon, we call a c -rfa, and then this is an alpha carbon, and in one side it connects with an amino group, nh2.
00:29
On the other side, it connect with a coboxy group, c -o -o -h.
00:34
And, of course, on top, it has a hydrogen group.
00:37
So these are the common structure of all amino acid.
00:41
Doesn't matter which one.
00:42
They all have these four parts.
00:45
And, of course, there is a side chain r.
00:48
The side chain is different in different amino acid...
