New mathematical model describes the structure of proteins

Proteins are the workhorses of our cells. They help to digest our food, are at the core of our immune system, and literally shape our body from top to toe. Proteins also play an important role in biotechnology in the form of enzymes, which are important in the creation of anything from pharmaceuticals to bread, washing powder and much more. Their possibilities are virtually without limit.
