Biomolecules and Enzymes
A bowl of rice, a piece of paper and a strand of your own hair look nothing alike, yet burn to the same few elements. Living things are built from a small set of molecules: sugars, fats, amino acids and nucleotides, joined into starch, proteins and DNA. In this chapter you analyse what a cell is made of, see how the building blocks join, learn how proteins fold and nucleic acids store information, and meet the enzymes that run every reaction in the body. Python counts atoms, builds peptides and fits enzyme curves.

The Chemical Composition of Living Things
How a tissue is analysed for its elements and compounds, and the primary and secondary metabolites. Then the four classes of biomacromolecule, amino acids and the four levels of protein structure, and sugars, polysaccharides and lipids.
Nucleic Acids, Metabolism and the Living State
Nucleotides and the structure of DNA and RNA, and the bonds that join each kind of monomer. Then metabolism as anabolic and catabolic pathways, ATP, and the living state as a steady state that is not equilibrium.
