Monoamine oxidases are a type of enzyme.
00:05
This question is asking which of our options, a, b, or c, would be, would a monoamine oxidase most likely act on? it's asking what would be the substrate.
00:17
Remember, the enzyme is the catalyst part.
00:20
The substrate is what the catalyst acts on.
00:25
The substrate is the reactant that's going to go through a reaction.
00:29
The enzyme is what's going to speed up that.
00:31
Reaction.
00:32
Now the name of an enzyme often tells you what the substrate is.
00:38
So monoamine oxidase, that ace ending tells you that we're talking about.
00:43
And this name is referring to an enzyme.
00:47
Monoamine is trying to tell you what the substrate must look like.
00:51
So we're looking for something that would be a monoamine.
00:56
Right.
00:57
Now let's get those options drawn out here.
00:59
There's quite a bit happening in these three options here.
01:07
And that is probably where any confusion would come from because most molecules are not just a single, right, functional group.
01:18
In reality, proteins are much, much larger.
01:21
In fact, most of these molecules that are actual proteins, this would be a very small part of a real monoamine protein.
01:31
If you look up pictures of these, there's thousands of amino acid.
01:34
Involved.
01:35
They're actually huge.
01:37
I'm just kind of rambling while i get this thing drawn out.
01:41
Okay, i'm going to draw this as it would actually and draw b a little bit here on the end.
01:47
So you can see a little bit more what that would look like.
01:50
And then we have c, which is this guy with an no2.
02:01
All right, so monoamine.
02:03
Mono means one.
02:04
Amin is a certain type of functional group, right? it involves a nitrogen, which is probably why there's nitrogen in all three of these.
02:10
Now, specifically, an amine is when you have a nitrogen and it can have up to three things attached to it.
02:23
These can be carbons...
