Chapter 5: A Preview

Chapter 5 focuses on the function and structure of macromolecules. There are 4 types of macromolecules this chapter focuses on in particular:

1. Carbohydrates
2. Lipids
3. Proteins
4. Nucleic Acids

We visited most of these when learning about the human digestive system, but now we will view them in the context of their structure and function on the molecular level rather than how they can be broken down and absorbed.

Here are some details about these building blocks of life:

Carbohydrates

Fuel and building materials. Sugars serve as fuel and carbon sources

Lipids

Versatile hydrophobic molecules. Fats allow for energy storage.

Proteins

Proteins have many structures and functions. Proteins can be made to preform almost any function.

Nucleic Acids

The biological code. Nucleic acids serve as the components of DNA
