Polymers make up many of the materials in living organisms, and they constitute the basis of certain minerals and human-made materials, such as paper and plastics. We report the discovery that heat can be used to reversibly cycle a protein between its polymeric and monomeric states. (non covalent exceptions ignored). They lower the energy needed for such reactions to occur in the cell. and their corresponding bioconjugates inherit that ability, obtaining a triggered (and commonly reversible) amphiphilic character. 5 years ago. 50 terms. Milk proteins (caseins and whey proteins) are important protein sources for human nutrition; in addition, they possess important natural polymers. Biodegradable protein-based engineering polymers are challenging alternatives. Yet little is known about how the phase behaviour of a protein is encoded in its amino acid sequence. Created by. Control of protein and cell attachment is vital to the performance of biomaterials, but silk fibroin is mostly hydrophobic and interacts nonspecifically with cells and proteins.
