If UV light is required for Vitamin D production does this make UV a Vitamin D precursor?

No UV light can not be treated as vit D precursor as it only provides the energy in the form of radiation for the reaction to take place. It is the steroid molecule present in dermis which is precursor for vitD synthesis.

How does vitamin D production play a part in the integumentary system?
the keratinocytes in the epidermal, when it exposed to UV light produce vitamin D
A vitamin that is easily destroyed by light and irradiation is?
vitamin A
What causes vitamin D production?
The Sun gives off light. The body uses light to convert 7-dehydrocholesterol into pre-vitamin D3. Pre-vitamin D3 forms in to cholecalciferol, vitamin D3. Vitamin D3 is brought to the liver were it forms 25-hydroxyvitamin D. Finally, it is brought to the kidney to form 1,25-dihydroxyvitamin D, the active form of vitamin D.
What is vitamin manufactured in skin?
Vitamin D has two forms which are vitamin D2 (ergocalciferol) and vitamin D3 (cholecalciferol). Vitamin D without a subscript refers to either D2 or D3 or both.Vitamin D3 is produced in the skin of vertebrates after exposure to ultraviolet B light.
Artificial light vs sunlight?
Artificial light is not always as good as natural sunlight. There are a few types of natural sunlight bulbs that come close, only they are still missing several wavelengths that are found in natural light. These wavelengths are necessary for plant growth and vitamin D production in animals.
What begins when a precursor molecule is exposed to ultraviolet light in the skin?
Vitamin D production begins when a precursor molecule is exposed to ultraviolet light in the skin.
What effects does vitamin A have on a body?
Vitamin A is the precursor for the pigments in the rod and cone cells of the eyes that detect light. With it you can see, a deficiency can cause blindness. However too much vitamin A can be toxic and it builds up in fat. To prevent toxicity supplements do not actually contain vitamin A, instead they contain Beta Carotene a precursor of vitamin A that is nontoxic and that the body converts as it needs vitamin A.
What vitamin is synthesized in the skin with exposure to the sunlight?
Vitamin D is produced by ultraviolet radiation on your skin. The UV light converts a precursor molecule to vitamin D.
How does vitamin D production play a part in the integumentary system?
the keratinocytes in the epidermal, when it exposed to UV light produce vitamin D
What system covers the external surface of the body and manufactures vitamin D?
The absorption of UV light into the skin converts a precursor molecule into vit. D
What wave can cause skin cancer and promote vitamin D production?
Ultraviolet radiation, also known as UV light, can cause both skin cancer and Vitamin D production. This type of wave comes from our Sun.
Is it true that ultraviolet radiation stimualtes the skin to produce anitibodies?
No; ultraviolet radiation stimulates the skin to produce melanin. UV light also converts a precursor to vitamin D in the skin.
Which vegetables have vitamin D?
Mushrooms provide vitamin D, if exposed to just 5 minutes of UV light after being harvested; this is one of a few natural sources of vitamin D for vegans. Very few foods are naturally rich in vitamin D, and most vitamin D intake is in the form of fortified products including milk, soy milk and cereal grains.Another answer:None. There are no vegetables that are naturally a source of vitamin D. Products like soy milk, almond milk, orange juice and breakfast cereals are enriched with vitamin D. Some mushrooms and fission yeasts contain a vitamin D precursor, ergosterol, that can be converted to vitamin D2 with exposure to ultraviolet light (specifically UV-B).Vitamin D3 is an animal product derived from 7-dehydrocholesterol upon exposure to UV-B. 7-dehydrocholesterol is synthesized in animals along with cholesterol, and each can be converted to the other. Vitamin D3 dietary supplements are typically produced by exposing lanolin (washed from freshly shorn wool) to UV-B in a production facility. Because animals produce the precursor and convert it to vitamin D3 by the simple act of being under the Sun, it is not required in the diet, provided you receive enough direct exposure to sunlight, and so is not a true vitamin.
Is Vitamin D production aided by the skin?
Yes.When the skin is exposed to sun light for an extended period of time (at least a half hour) it will begin converting cholesterol to Vitamin D. This process will continue as long as it is exposed to sufficiently strong sun light.
How is light related to Vitamin C?
Vitamin C is sensitive to light, air and heat.
A vitamin that is easily destroyed by light and irradiation is?
vitamin A
What vitamin is sensitive to light?
Vitamin A, Vitamin B12, Vitamin D, Folic Acid, Vitamin K, Vitamin E, Pyridoxine, Riboflavin
