AP Biology Unit 1: Chemistry of Life — Mind Map

Reviews water's properties (polarity, hydrogen bonding, cohesion, adhesion), the four classes of biological macromolecules (carbohydrates, lipids, proteins, nucleic acids), monomers and polymers, dehydration synthesis and hydrolysis, protein structure (primary through quaternary), and the role of enzymes.
