Keratin is a tough, fibrous protein. There are two types of keratin: alpha- and beta-keratin. Alpha-keratin is softer and is found only in mammals.
Alpha keratin has alpha helix structure and beta keratin has beta pleated sheet structure.
Alpha keratin is a protein present in hair,wool,nails, horns,hooves of mammals
Keratin is a type of fibrous protein, which is a macromolecule composed of long chains of amino acids. It is a key structural component found in hair, nails, and the outer layer of skin, providing strength and protection. Keratin exists in various forms, including alpha-keratin and beta-keratin, depending on the organism and its specific structural functions.
alpha can be translated as the letter "A" in the greek alphabet, but also used as first. keratin are a family of fibrous structural protein
Alpha-Keratin
It forms in your hair and finger nails.
Keratin is a fibrous structural protein that forms the key structural material in hair, nails, and the outer layer of skin in humans and many animals. It provides strength, protection, and resilience, making it essential for maintaining the integrity of these tissues. Keratin exists in various forms, including alpha-keratin and beta-keratin, which differ in their structural properties and functions. Its durability also contributes to the waterproofing of skin and the overall barrier against environmental damage.
In the natural unstretched state the hair is Alpha Keratin and when the hair has been styled in the unnatural state it is beta keratin. When blow drying for example the keratin in the alpha keratin is changed to beta keratin, causing the hair to temporarily in its new shape. Once the hair takes in moisture from the atmosphere or becomes wet, it reverts back to the normal state
I believe it is because of the alpha helix spiral structure of the molecule and the weak hydrogen bonds that create elasticity.
Another name for keratin is "fibrous protein." It is a key structural protein found in hair, nails, and the outer layer of skin, providing strength and protection. In some contexts, keratin can also refer to specific types, such as "alpha-keratin" or "beta-keratin," depending on its structural configuration.
