ABSTRACT
In its general acceptation, biopolymers are polymers produced by living organisms. The two main characteristics encountering here are: to be a polymer, e.g., to have repeating (monomer) units; and to be produced by living organisms, e.g., to be produced from a deoxyribonucleic acid encoded information. Hydrophobic interactions in cellular processes support the idea that the thermodynamic potential arising from an incompatibility of organic compounds with water is likely to be the driving force of evolution. Thus, the hydrophobicity is responsible for a multitude of biological facts. A series of biopolymers based bio-composites are synthesized by the living organisms and are currently used as is or with minimal chemical treatment. Depending on the nature of the prebiotic environment, available building blocks may have included amino acids, hydroxy acids, sugars, purines, pyrimidines, and fatty acids. These could have combined to form polymers of largely random sequence and mixed stereochemistry.
