Hi there.
00:03
Let's talk about amino acids.
00:06
Amino acids are molecules that serve as the building blocks for proteins.
00:17
So when we link amino acids together, we can make proteins.
00:22
And proteins are, of course, used as catalysts in living organisms.
00:28
But let's talk about what an amino acid really is.
00:31
Amino acid contains two functional groups.
00:35
There is an amino group, or in other words, amine and a carboxylic group, carboxylic acid group.
01:01
Let's look at what that might look like.
01:06
So we have carbon bonded to r.
01:09
Remember, r is a chain.
01:11
It can be hydrocarbons, just carbons and hydrogens, or it might be carbons with hydrogens, oxygen, sulfurs.
01:18
This is the part of an amino acid that can vary, the r group.
01:24
And there's a hydrogen...
