Detailed explanation-1: -Keratin is a protein that helps form hair, nails and your skin’s outer layer (epidermis).
Detailed explanation-2: -Keratinocytes (ker-uh-TIH-no-sites) make keratin, a type of protein that’s a basic component of hair, skin, and nails. Keratin in the skin’s outer layer helps create a protective barrier.
Detailed explanation-3: -Keratin is the main structural protein that forms the hair, wool, feathers, nails, and horns of many types of animals [83]. The protein has high contents of cysteine (7%–20% of the total amino acid residues), which is known to form intramolecular and intermolecular disulfide bonds [84, 85].
Detailed explanation-4: -Hair is a filamentous biomaterial consisting mainly of proteins in particular keratin.
Detailed explanation-5: -Keratin (/ˈkɛrətɪn/) is one of a family of structural fibrous proteins also known as scleroproteins. Alpha-keratin (-keratin) is a type of keratin found in vertebrates. It is the key structural material making up scales, hair, nails, feathers, horns, claws, hooves, and the outer layer of skin among vertebrates.
