No, keratin is a type of protein that makes up hair, skin, and nails. Skin color is primarily determined by melanin, a pigment produced by specialized cells called melanocytes in the skin. Keratin and melanin are produced by different cell types and have separate functions in the skin.
Keratin is produced by special cells in the skin called keratinocytes. These cells synthesize keratin protein from amino acids, which are the building blocks of protein. The keratin proteins are then assembled into fibers that provide structural support and protection to the skin, hair, and nails.
Melanin is formed by the melanocytes which are in the stratum basale of the epidermis. Keratin is formed by the epithelial cells of the skin in the epidermis.
Hair is composed of a protein called keratin, which is produced by hair follicles in the skin.
Keratin is the protein that strengthens and waterproofs the epidermal layer of the skin.
where in the skin would you find keratin?
Keratin
Hair is made up of a protein called keratin, which is produced by hair follicles in the skin.
The penetration power of less energetic UV radiation isn't that high, and is usually stopped by melanin and keratin. Melanin is produced by a certain type of cell in the skin and deposited in live outer layer skin cells above their nucleus. Keratin is produced by dying outer skin cells and deposited over them, offering further shielding of live cell's nucleai.
Hair is made from a protein called keratin, which is produced by hair follicles in the skin. Keratin helps to make hair strong and flexible, while also providing insulation and protection.
Skin cells produce a protein called keratin, which is a key structural component of hair, nails, and the outer layer of skin.
The tough waterproof protein found in skin, hair, and nails is called keratin. Keratin provides structure and protection to these tissues.
