This chapter asks what living things are made of. It shows how a tissue is taken apart into an acid-soluble pool of small molecules and an acid-insoluble fraction of large ones, and meets the small building blocks: amino acids, fatty acids and glycerol, sugars, nitrogen bases, nucleosides and nucleotides. It then builds them into the three true macromolecules, proteins, polysaccharides and nucleic acids, describes the four levels of protein structure, and ends with enzymes: how they lower activation energy, what affects their activity, how they are classified and which co-factors they need.
