Macromolecules
Macromolecules are large molecules built up from small units (monomers). Different macromolecules have different units and/or different linkages (that’s all you have to know!) For example glucose (the small unit) can join together to make starch or cellulose (natural macromolecules). (NOTE: diamonds are other examples of macromolecules).
Examples of the small units:
-glucose
-amino acids
-fatty acids and glycerol
Examples of linkages:
-amide
-ester
Examples of macromolecules:
-protein
-starch
-lipids
