Melanin and carotene are skin pigments that help block damaging rays from the sun. The more of these pigments in the skin the greater the protection.
Keratinocytes or squamous cells produce keratin and Melanocytes produce melanin, pigment.
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.
No, It is keratin, That is what all hair on mammals is made of.
Epidermis-Which is the thin, cellular, multilayered membrane that produces MELANIN and KERATIN.
its mostly made of protein: keratin and some melanin
not on its own. hair has metabolites in the hair or keratin and in the melanin or color granules. the "bleaching" (done with peroxide) will take care of the melanin but you will need a good toxin system like hair razor for the keratin.
Skin- melanin. Hair- keratin.
Keratin refers to a family of fibrous structural proteins. Keratin is the key structural material making up the outer layer of human skin.Melanin is a pigment which gives color to 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.
No, hair color is determined by the amount of melanin produced.
The answer: a
