It's time to start learning about all the monomers that make up large biomolecules, and the first one to learn about is the amino acid in this lesson!

Everyone has heard of proteins, but what are they on the molecular level? In this chemistry lesson, learn how proteins are polymers of amino acids.

What are enzymes? Why, they're nature's little factory workers. Learn how they chop up certain things and build up others in this chemistry lesson.

Everyone knows about carbohydrates and sugars! In this chemistry, learn about the linear and cyclic forms of monosaccharides (aka carbs and sugars).

Now that you know about simple sugars, learn about how these polymerize to form long polysaccharide chains like cellulose, starch, and glycogen.

In this chemistry lesson, learn about lipid structures and examples, then find out about saturated and unsaturated fats, and why to stay away from trans fats.

Steroids get a pretty bad rap. In reality, this class of molecules include many vitamins, as well as cholesterol. Learn about steroids in this chemistry lesson.

A cell's membrane is the reason behind any living organism's existence. In this biochemistry lesson, learn all about the cell membrane and how it works.

Did you know that cells can talk to one another? Learn how sending and receiving works within the cell membrane in this biochemistry lesson.

What are nucleic acids and what do they have to do with DNA and RNA? In this biochemistry lesson, learn what makes up the genetic code of living organisms.
