Chemistry of Life
Discover how atoms and molecules—like DNA, proteins, and sugars—interact through chemical reactions to build cells, store energy, and create the blueprint for life itself.
Key Concepts to Master
1.1 Structure of Water and Hydrogen Bonding
Water's polar structure and hydrogen bonding give it unique, life-supporting properties like cohesion, temperature regulation, and surface tension.

Watch Now1.5 Structure and Function of BM
Macromolecules' structures dictate functions: carbs (energy), lipids (membranes), proteins (catalysts/structures), and nucleic acids (genetic code) collectively sustain life.
