Keratin is found naturally in a variety of animal-derived sources, and is primarily a structural protein.
Natural Sources of Keratin
Keratin is not a single substance but rather a family of proteins that are found in many natural materials of animal origin. Here are some key sources:
Animal Sources
- Chicken Feathers: Keratin is a major component of chicken feathers.
- Beaks: Bird beaks contain keratin, providing them with their hard structure.
- Claws: Claws of various animals are made of keratin.
- Nails: Both human and animal nails contain keratin.
- Horns: Horns of animals like cows and rams are primarily made of keratin.
- Hooves: Hooves of animals like horses and cattle contain keratin.
- Hair: Human hair and the fur of many animals contain keratin.
- Toenails: Similar to fingernails, toenails are primarily made of keratin.
Other Sources
- Wool: Wool fibers are another significant source of keratin.
