In the last lecture, we began to look at macromolecules.
You learned about the four different classes of macromolecules,
as well as taking a deeper exploration into carbohydrates.
In this lecture, we’ll move forward beginning with the examination of proteins.
By the end of the lecture, you should be able to describe
the four levels of organization in protein structure
as well as explain how nucleotides come together to form DNA and RNA.
And finally, you should be able to discuss the major classes of lipids.
Proteins are by far the most diverse category of macromolecules.
Proteins are enzymes, they’re involved in the structure of cells,
they’re also involved in storage, and signaling,
as well as transport, and regulation.
