Keratin is a type of protein that is found in various parts of the body, primarily in structures that provide protection and support.
Here are some key locations where keratin is found:
- Hair: Keratin forms the main structural component of hair, contributing to its strength and flexibility.
- Nails: Similar to hair, nails are primarily made of keratin, giving them their hard and protective qualities.
- Outer Layer of Skin: Keratin is abundant in the epidermis, the outermost layer of the skin, creating a tough barrier that shields the body from external factors like microbes and environmental damage.
- Internal Organs: Keratin is also present in the linings of organs, glands, and other internal tissues, playing a protective role within the body.
- Other Structures: In various animals, keratin is also responsible for forming hooves, claws, horns, and scales.
In essence, keratin is a fundamental protein responsible for the integrity and protection of various structures throughout the body.
