Abstract

Polymers are generally categorised into two main categories: natural or synthetic. Natural polymers occur in nature and are can be extracted, studied and replicated for global use for diverse application: from pharmaceuticals to cosmetic industries. Nature has, through billions of years of evolution, assembled a vast number of polymeric macromolecules capable of exquisite molecular recognition. These functionalities within naturally occurring polymers, arise from the precise control exerted over their biosynthesis that results in key residues being anchored in the appropriate positions to interact with target substrates. Examples of common and widely studied natural polymers are silk, wool, DNA, cellulose and proteins. Nucleic acids, such as DNA and RNA, display ordered sequences based on four-nucleotide monomer units, whilst in proteins, 20 amino acids (monomers) are used to form precisely controlled monomer sequences. Such precise positioning of monomer units (or functionalities) has an important influence on polymer structure and results in unique properties, such as molecular recognition which spans functions as diverse as the transport of oxygen by haemoglobin, the detection of pathogens by our immune system and the control of metabolic pathways by enzyme catalysts of enviable specificities.
