0 a dark brown pigment (= substance that gives colour), found in eyes, skin, hair, feathers, etc. It helps to protect the skin against harmful light from the sun. -- 黑色素
Melanin containing cells of teleost fish and their relation to disease.
Does melanin do more than protect from light?
It is suggested that the delayed production in hardness may be associated with the presence of a reducing chemical environment produced by antioxidant properties of melanins.
It leaks more slowly and, due to the stimulating wavelength, provides greater visualization of structures hidden by blood, exudate, lipid or melanin.
Our findings have implications for understanding the role of melanin or related agents in the process of mammalian retinal development.
The monotonic absorption profile with no specific features can be explained by the complexity of the melanin structure.
The snail tissue is also nearly transparent, except for the digestive gland and mantle tissue which is spotted with melanin.
The conjunctiva, sclera and iris are heavily pigmented with melanin granules and the iris contains gold-reflecting material, which is mostly obscured by the pigmented layer.
