Vitamin D exists as a fat-soluble vitamin (soluble in lipids). It exists as a hormone located in food and synthesized in the human body from a product of cholesterol or ergosterol under the act of UVB1 radiation from the Sun.
Linoleic acid exists as a polyunsaturated fatty acid, a kind of omega-6, located in vegetable oils, especially in safflower oil.
<h3>What are fat-soluble vitamins?</h3>
Vitamin D exists as a fat-soluble vitamin (soluble in lipids). It exists as a hormone located in food and synthesized in the human body from a product of cholesterol or ergosterol under the act of UVB1 radiation from the Sun.
In humans, it exists in two states: D2 (ergocalciferol) created by plants or D3 (cholecalciferol) from essentially animal sources or synthesized in the skin under the influence of ultraviolet rays. Some plants, especially lichens, also have the D3 state. These two molecules exist as 9,10-secosteroids.
Linoleic acid exists as a polyunsaturated fatty acid, a kind of omega-6, located in vegetable oils, especially in safflower oil.
It exists as an essential fatty acid, it must be carried to the body through food.
Its carbon chain consists of 18 carbon atoms, and two double bonds, one affecting the sixth carbon, and the other the ninth.
Its melting temperature exists at -9° C, which produces linoleic acid liquid at room temperature.
