Chemical molecules important to biology (biological molecules) are sometimes called macromolecules because they are large (‘macro’ means large). The four important classes of macromolecules we’ll study for this course are carbohydrates (sugars or ‘saccharides’), lipids, proteins and nucleic acids.
Common examples include the polyethylene used in trash can liners, the polyvinyl chloride used as wire insulation, and the polypropylene used in food storage ...

Polymeric materials and applications The phrase "polymer" descends from the Greek words (meaning "many") and meros, meaning "part", and its structure consists of large numbers of repeating molecules [3]. The modern thought of polymers as covalently linked macromolecular structures was projected in 1920 by H. Staudinger [4].
