Okay, welcome everyone. My name is Devine. This is episode 409 of the Devine

Intervention Podcasts. And to this podcast we're going to be discussing hemoglobin.

This is going to be the clutch hemoglobin podcast, the clutch hemoglobin. This is going to be the clutch hemoglobin podcast. If you know what's discussed here,

I will be surprised if you get any hemoglobin related questions wrong on your exam. So obviously this is a

podcast that will be useful for people taking the USMI- Step 1 to take 3 exam. Now, we all know that hemoglobin is the primary molecule that carries oxygen around in the blood, right?

It's the thing that basically its main primary job is that it's an oxygen carrier. It can carry other things or primarily

worried about it from the perspective that it's an oxygen carrier. Although, like I said,

can carry other things like carbon dioxide.

When it carries carbon dioxide, that's what's known as carbon amino,

hemoglobin, carbamino, c-a-b-a-m-m-ino hemoglobin,

carbamino hemoglobin, carbomino hemoglobin. Now hemoglobin, carbamineo hemoglobin.

Now hemoglobin, remember, is made of heme and four globin chains.

Those four globin chains essentially define the different kinds of hemoglobin

that you can find in blood.

So, for example, we have hemoglobin A, that's adult hemoglobin.

Remember, it contains two offers and two beatings. We have

hemoglobin F, that's the phytoh hemoglobin that contains two offers and

two garments. Fido hemoglobin we know that we find it when you're in utero and it lasts for about six months after you've been born.

That's why people with sickle cell disease and with many hemoglobinopathies don't have many problems, especially if you have like bitter phallosymia or whatever.

You won't have significant problems for about the first six months of life roughly because that hemoglobin F is wearing off.

But once the hemoglobin F wears off, then the person's problems will begin.

And we know that there is the drug known as hydroxia
