In nature, there are animals that make fibers which are strong and elastic. For example, the thread that spiders produce to make webs. These fibers have a polypeptide structure and serve as ...

Fibrous structures act as load-bearing components in vivo in many natural proteins besides enzymes, which are soluble globular molecules. Natural evolutionary processes have produced structural ...

The rippled sheet is a distinctive variation on the pleated beta sheet, which is a well-known structural motif found in thousands of proteins, including important disease-related proteins. Linus ...

Proteins are made of amino acid chains, or polypeptides. Amino acids have a basic backbone made of an amino group and a carboxyl group, and differ in their side-chains. These polypeptide chains of ...

Animals such as spiders make fibers which are strong and elastic. These fibers have a polypeptide structure and serve as inspiration for research into the development of functional materials.
