fibrous proteins

Fibrous proteins are long, string-like molecules that make up structural parts of our body, providing strength and support. Examples include collagen in skin and tendons, keratin in hair and nails, and elastin in stretchy tissues like blood vessels. They are characterized by their fibrous, sheet-like shapes and are usually insoluble in water, helping tissues withstand pulling and stretching forces. These proteins form the framework that maintains the shape and durability of various body parts, contributing significantly to the body's overall integrity and resilience.
