In this video, we're going to begin our introduction to biomolecules, and biomolecules can be defined as organic molecules that are going to have carbon and hydrogen atoms linked together covalently and that are essential to living organisms. We can tell that biomolecules are essential to living organisms because they have that root 'bio,' which means life. Now, there are actually 4 primary classes of biomolecules, and those 4 primary classes are listed down below. They are carbohydrates, proteins, nucleic acids, and lipids. Notice down below we have these four images of these four classes of biomolecules. What you'll notice is the image on the far left over here represents carbohydrates. This image represents proteins. The next image represents nucleic acids, and last but not least, the 4th image represents lipids. As we move forward in our course, we're going to talk more about each of these classes of biomolecules in their own separate videos. That being said, this here concludes our introduction to these biomolecules, and I'll see you all in our next video.

Biomolecules are essential organic molecules composed of carbon and hydrogen, crucial for life. The four primary classes include carbohydrates, proteins, nucleic acids, and lipids. Understanding their building blocks—monomers like monosaccharides, amino acids, nucleotides, and fatty acids—is vital. Carbohydrates can be simple or complex, while proteins have diverse structures. Nucleic acids, such as DNA and RNA, play key roles in genetic information, and lipids include fats and phospholipids, important for cell membranes. This foundational knowledge is critical for exploring biological processes and systems.

Map of the Lesson on Biomolecules
Video transcript
In this video, we're going to introduce our map of the lesson on biomolecules, which is down below right here. And so, because this is a map of our lesson, you can actually use this image like a map or a table of contents to make predictions about what we're going to cover next. And so, we're starting here at the top with biomolecules, and next, you should expect that we're going to cover monomers and polymers. And we'll talk about the different types of monomers, including monosaccharides, amino acids, nucleotides, and fatty acids. And then, we're going to explore the leftmost branches first. So, we'll talk about the carbohydrates first, distinguishing simple versus complex carbohydrates, oligosaccharides, and polysaccharides, and then after we finish talking about carbohydrates, we'll move on to talking about proteins and protein structure. Then we'll talk about nucleic acids, distinguishing DNA from RNA, and then last but not least, we'll talk about the lipids, talking about the different types of lipids such as fats, phospholipids, steroids, and waxes. And so, once again, this is a map of our lesson moving forward, so you should be referring to this map as we move forward in our lesson. Again, to be able to get a gauge of where we are within the lesson and what we're going to be covering next. And so, this concludes our introduction to our map of the lesson on biomolecules, and I'll see you all in our next video to talk more about these monomers and polymers.
