Rhino horns, for example, are mostly made of keratin, the same fibrous protein found in human hair and fingernails, but people in some cultures still think of them as an aphrodisiac.
Collagen, a fibrous protein found in connective tissue, bone and cartilage, basically holds the body together.
Young skin, supple and resilient owing to its abundant collagen and elastin (fibrous proteins that act as a strong yet stretchy scaffolding), easily snaps back into place.
Inflammation calls more immune cells to the wound to help fight infection, along with collagen, a fibrous protein, to help seal the wound shut.
This is an example of HOW the secondary structure of fibrous proteins could help the food industry.
