Question

What are lipids soluble in?

Answer 1

Hint: Lipids are those compounds which can dissolve in the solvents with a uniform electron distribution, i.e. the compounds which have evenly distributed electrons from the centre of the atom.

Complete answer:
The lipids are chemical compounds which are classified as a macromolecule which is insoluble in those compounds with a polar nature. The non polar solvents have the ability to dissolve all the kinds of lipids, that is fats, oils, wax, phospholipids and steroids. Generally, the organic compounds do not dissolve lipids but in case of organic compounds with a symmetrical structure and a net polarity of zero, the lipids become soluble. these compounds are four in number and include:
1. Acetone
2. Benzene
3. Chloroform
4. Ether
The polarity in compounds develops when the electrons of the compound have an uneven orientation from the central atom of the compound. The polarity is mainly a property of covalently bonded compounds, such as water and Hydrogen Fluoride. The covalent compounds have a low boiling point and the covalent bonds can be broken very easily.
The non polar compounds are the ones in which the electrons are quite symmetrically oriented.

Note:
There are four types of vitamins in the human body which are lipid soluble. These are:
1. Retinol (Vitamin A)
2. Cholecalciferol (Vitamin D)
3. Tocopherol (Vitamin E)
4. Phylloquinone (Vitamin K)
