MICROANATOMY

Detailed explanation-1: -What is keratin? Keratin is a protein that helps form hair, nails and your skin’s outer layer (epidermis).

Detailed explanation-2: -keratin, fibrous structural protein of hair, nails, horn, hoofs, wool, feathers, and of the epithelial cells in the outermost layers of the skin. Keratin serves important structural and protective functions, particularly in the epithelium.

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.

Detailed explanation-4: -Your epidermis is the top layer of the skin that you can see and touch. Keratin, a protein inside skin cells, makes up the skin cells and, along with other proteins, sticks together to form this layer.
