In this video, we're going to begin our introduction to biomolecules. Now, biomolecules are defined as organic molecules that have covalently linked hydrogen and carbon atoms, and they are essential to living organisms. We can tell that biomolecules are essential to living organisms because it has this bio root. Now really there are four primary classes of biomolecules that you all should be aware of, and these are the carbohydrates, the proteins, the nucleic acids, and the lipids. Notice, down below, we're showing you some images that are used to represent the different classes of biomolecules.
Over on the far left, this image here is representing the carbohydrates, the second one here is representing the proteins, the third one is representing nucleic acids, and last but not least, the fourth one over here is representing lipids.
Moving forward in our course and in their own separate videos, we'll get to talk more about each of these different classes of biomolecules in a lot more detail. So this here is just the introduction to these molecules, and we'll get to talk more about them moving forward.
So, I'll see you all in our next video.
