It forms in your hair and finger nails.
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
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 is the structural protein of hair
it is the structural protein of hair
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.

Keratin and Collagen are examples of proteins.
