Classic compounds include zinc oxide and titanium dioxide, used in a variety of sunscreens and sunblocks. A synthetic chemical, PABA (4-aminobenzoic acid) is also in use, primarily as insoluble "Padimate O" after some studies suggested photocarcinogenic effects.

What pigment absorbs ultraviolet light?
There are many pigments that absorb light energy. They are as follows:Carotene - an orange pigmentXanthophyll - a yellow pigmentChlorophyll a - a blue-green pigmentChlorophyll b - a yellow-green pigmentPhaeophytin - a gray pigmentThese are all/most of the pigments in a leaf that absorb light energy.!!
What is the function of malanin?
Melanin is a pigment that gives color to the hair, skin, and eyes. Its main function is to protect the skin from the harmful effects of ultraviolet (UV) radiation from the sun by absorbing and scattering the UV radiation.
What pigment prevents the radiation from harming structures in the under layer of the skin?
Melanin is the pigment that protects structures in the under layer of the skin by absorbing and scattering harmful radiation from the sun, such as ultraviolet (UV) rays. Melanin helps to prevent damage to DNA in skin cells and reduces the risk of skin cancer and premature aging.
What links a suntan to the EM spectrum?
A suntan is linked to the electromagnetic spectrum because sunlight contains ultraviolet (UV) radiation, which is a form of electromagnetic radiation. When the skin is exposed to UV radiation from the sun, it triggers the production of melanin in the skin, leading to a suntan as a way for the skin to protect itself from further damage caused by UV radiation.
Which type of radiation can cause a suntan?
Ultraviolet (UV) radiation can cause a suntan. When the skin is exposed to UV radiation from the sun, it stimulates the production of melanin, a pigment that darkens the skin to provide some protection against further damage.
Is a plant pigment that absorbs most wavelength of light?
The ozone acts like a sunblock for the earth, so it absorbs most of the ultraviolet radiation.
Is melanin the pigment producing cell?
Melanin is a pigment produced by cells called melanocytes. These cells are found in the skin, hair, and eyes, and are responsible for giving these tissues their color. Melanin helps protect the skin from the harmful effects of ultraviolet radiation.
Which substance in a chloroplast is a green pigment that absorbs energy for photosynthesis?
The green pigment is called "chlorophyll".
What protective pigment provides a protective umbrella overtge nucleus of the cell?
Melanin is the protective pigment that acts as an umbrella over the nucleus of the cell, shielding the DNA from damage caused by ultraviolet radiation.
A dark colored pigment that protects from the ultraviolet light is called?
Pigment that protects from the ultraviolet light is called melanin. This is science.
What effect does ultraviolet radiation have on skill cells?
affects the production of Vitamin Dtriggers the production of Melanie (dark pigment)Triggers cancer fighting mechanisms.The higher energy Ultraviolet UVc is responsible for sunburn and melanoma.
Why does the skin tan in the sun?
It's a defence mechanism against the Sun's harmful UV radiation, using the pigment melanin.
