MICROANATOMY

Detailed explanation-1: -Keratin is a protein that helps form hair, nails and your skin’s outer layer (epidermis). It helps support your skin, heal wounds and keep your nails and hair healthy.

Detailed explanation-2: -Fingernails are mostly made up of a hardened protein called keratin. Keratin is the same stuff which makes up hooves, claws and horns in animals. It’s also found in our very own hair and skin.

Detailed explanation-3: -Keratin, like all proteins, is made up of amino acids. Each protein contains its specific order of amino acids, much like each person contains its string of deoxyribonucleic acid (DNA). While keratin can also be found in internal organs and glands, they are primarily found in epithelial cells.
