The structure and function of globular proteins You don’t need to be an aeronautical engineer to know that a plane’s ability to fly depends on more than just the parts that it’s built from. A powerful engine, well-designed wings, and an aerodynamic body are all necessary for flight—but they aren’t sufficient. A summary of Globular and Fibrous Proteins. Very useful as exam/test preparation. Made for OCR, but can be used across syllabus.

In a globular protein, the amino acid chain can twist in a way that polar groups lie at the protein's surface. This allows the protein to interact with water and enhances the protein's solubility in water. This does not occur in fibrous proteins, so fibrous proteins are insoluble in water. Like actin, amelogenin is a globular protein that self-assembles into nanospheres, that then form linear nanochains. This self-assembly process is thought to be the driving force for formation of parallel bundles of apatite during enamel formation, and regulates calcium phosphate crystal growth.
