SSC MTS EXAM

Detailed explanation-1: -They are water insoluble. Lipids are non-polar molecules while water is polar molecule, so there is no way for water to attach to a lipid molecule. Instead, the non-polar lipids will bind to themselves, which is why oils and fats form droplets on the surface of water.

Detailed explanation-2: -Lipids are all insoluble in polar solvents like water but highly soluble in the non-polar or weakly polar organic solvents, including ether, chloroform, benzene, and acetone. In fact, these four solvents are often referred to as “lipid-solvents” or “fat-solvents".

Detailed explanation-3: -Lipids are chemical substances that are nonpolar in nature. Because water is a polar molecule, they are only soluble in nonpolar solvents and insoluble in water. These molecules can be produced in the human body and are found in oil, butter, whole milk, cheese, fried meals, and some red meats.

Detailed explanation-4: -This is because the electrons in the covalent bonds are shared equally between the carbons and the hydrogens and there are no partial charges anywhere. Thus, long chains of carbon-hydrogens bonds form a nonpolar molecule.
