Summary
Biochemistry is the chemistry of life — proteins, DNA, metabolism, and how cells turn food into work.
Central dogma: DNA → RNA → protein. Enzymes speed reactions; ATP is the cell's energy currency.
- Four macromolecules: proteins, carbs, lipids, nucleic acids.
- Molecular shape determines function — misfolding causes disease.
- Glycolysis + mitochondria → most of your ATP.
