Unit 1 introduces all chemistry concepts that need to be applied to biological principles. The key elements are named, macromolecules are defined, and the characteristics of the chemical contribution to life are laid out. The content in this unit can be a bit dry, with a focus on vocabulary and more detailed chemical applications than are seen in other aspects of the course. A lot of processes discussed in later units depend on a strong understanding of this unit.
