About Macromolecules
Proteins are classified by shape, composition and structure, from primary amino acid sequence to secondary, tertiary and quaternary organisation, and their biological roles are linked to this structure. Enzymes are examined as protein biocatalysts, including active sites, substrate specificity, activation energy, cofactors and factors affecting activity.
