WebMost proteins have one highly stable tertiary structure, which is often organized around a core region of hydrophobic residues. However, if you denature proteins (e.g. by heating them up) and then let them cool they usually fail to reform into the 'correct' structure - instead they stick to each other. WebStructural proteins are proteins that living organisms use to maintain their shape or structural integrity. Similarly, other organic compounds like carbohydrates can be structural. Some common structural proteins are keratin, collagen, actin, and myosin. Proteins come in different sizes and shapes.
