Biochemistry — three ways to learn it.

The complete written lesson — the biomolecules of life: carbohydrates, proteins (the peptide bond & protein structure), lipids & the cell membrane, enzymes & the lock-and-key model, nucleic acids (DNA, RNA & base pairing), and vitamins.

As you scroll, a live D3 panel animates every idea: a glucose ring and a reducing-sugar colour change, two amino acids forming a peptide bond, a protein chain folding, a rotating DNA double helix, and a hero scene where a substrate locks into an enzyme's active site.

Run an enzyme activity vs temperature experiment on a guided 3D bench: warm catalase + H₂O₂, watch substrate lock into the active site and O₂ bubbles rise, then plot the bell-shaped rate curve with its optimum at 37 °C. Tap any part for its name, explanation and an Ask AI button.
