Learn about melanin. Understand what melanin is, how melanin is produced, its types, its function, and some issues concerning the expression of...
In the hair-covered general body skin of adult pigmented mice, melanogenically-active melanocytes are largely restricted to the bulbs of growing hair follicles. After cutaneous applications of appropriate c...
These superficial keratinized cells are continuously replaced by cells derived from mitotic cells in the lowest layer of the epidermis (i.e., the basal layer). Melanocytes locate in the basal layer and do not keratinize; however, they can produce melanin pigments. Melanin is accumulated in ...
Melanin pigments that produce mainly black or dark colors are common sources of skin, hair, and plumage colors of animals (Jawor and Breitwisch2003; McGraw2006). Because these colors are often perceived as dull or cryptic, much research has focused on their non-sexual functions, e.g., streng...
Based on the basic mechanism of tea polyphenol in the health care function, the anti-oxidative ability of tea polyphenol is based on the removal of excessive free radicals in the body. It has the function of synthesizing the human body to protect the health of the human body.Main ingredients...
However, if the energy input is too great, the output can be expressed in the form of activated chemical species that can damage cellular macromolecules resulting in cell death, mutations and cancer. The protective aspect of melanin in dark skin is seen as resulting from its high concentration ...
Structure and function of melanocytes: microscopic morphology and cell biology of mouse melanocytes in the epidermis and hair follicle. Melanocytes characterized by their tyrosinase activity, melanosomes and dendrites locate in the basal layer of epidermis and hair bulb in the skin of mice... T Hir...

Melanin, which is responsible for virtually all visible skin, hair, and eye pigmentation in humans, is synthesized, deposited, and distributed in subcellular organelles termed melanosomes. A comprehensive determination of the protein composition of this organelle has been obstructed by the melanin prese...
