In life that has all these carbon, hydrogen, nitrogen and oxygen are proteins.
00:14
Proteins are those molecules that contain all of these elements.
00:17
Look here.
00:18
Look at the basics of building block for proteins, which are amino acids.
00:26
Now look at the basic structure of an amino acid.
00:29
Right? i'm going to draw it here.
00:31
We have carbon linked to another carbon protein.
00:35
Probably.
00:37
And this is the caboxyl group here.
00:40
Okay.
00:42
And we have the functional group, r group there, which is a variant.
00:46
You have the hydrogen linked there.
00:49
We have nitrogen there, linked to other hydrogen molecules.
00:58
Okay.
00:58
And those are amino...
