melanin is black pigment found in the epidermis
Melanin
Melanin
The dark green pigment produced from hemoglobin when red blood cells are destroyed is called biliverdin. It is eventually converted into bilirubin, which gives bile its yellow color.
The dark pigment of Rhizopus is concentrated in the sporangia, which are the spore-producing structures of the fungus. This pigment is typically found in the sporangiospores, which are the asexual spores formed within the sporangium.
The layer in the eye that contains dark pigment to absorb extra light and keep the inside of the eye dark is the choroid layer. The melanin pigment in this layer helps prevent light from scattering inside the eye, allowing for better vision and reducing glare.
The cells that produce the pigment in hair are called melanocytes.
The condition of unusual deposits of black pigment in the body tissues or organs is called melanosis. Melanosis can be caused by various factors such as medications, heavy metals, or underlying medical conditions. Treatment depends on the underlying cause and may involve addressing the root issue or managing symptoms.
The main pigment of the skin is melanin, it is what makes your skin light or dark whether it be your ethnicity or even the amount of exposure you get from the sun.
Pigment that protects from the ultraviolet light is called melanin. This is science.
Because cattle are warm blooded animals they contain a pigment in their meat tissues called myoglobin. This pigment is normally a dark grayish color, which then creates the dark color in beef.
Dark brown pigment is commonly referred to as "umber." It is a natural pigment made from clay containing iron oxide and manganese oxide, resulting in its rich brown color. Another dark brown pigment is "burnt sienna," derived from heated sienna clay. Both pigments are widely used in art and various industrial applications.
The pigment found in bile is called bilirubin. It is produced during the breakdown of red blood cells in the liver and gives bile its yellow to dark green color.
I believe you're referring to melanin. Yup, melanin, and it is more than just dark brown and black pigment. Melanin is the primary determinant for all colors found in skin and hair, including reds and blondes. Forms of melanin range from iris color to the ink that a squid produces. Think of grey hair as lacking melanin.
cos it covers the nipple and contain dark pigment and have sweat glands
The dark green pigment produced from hemoglobin when red blood cells are destroyed is called biliverdin. It is eventually converted into bilirubin, which gives bile its yellow color.
The pigment containing iron is called hemoglobin. Hemoglobin is a protein found in red blood cells that carries oxygen throughout the body.
melanin
The specialized epithelial cells that produce a dark pigment are called melanocytes. These cells are primarily located in the skin, hair follicles, and the retina of the eye. Melanocytes synthesize melanin, the pigment responsible for skin and hair color, as well as protection against ultraviolet (UV) radiation.
They don't have the gene that leads to the creation of the protein for coloring.
