HUMAN NUTRITION

Detailed explanation-1: -Answer and Explanation: The characteristic that all lipids have in common is that they are nonpolar molecules, which means they do not dissolve in water.

Detailed explanation-2: -Most lipids are non-polar (having no charged areas) or only slightly polar, with a very few charged areas. Water mixes with hydrophilic (water-loving) compounds by sticking to their charged groups. Since lipids lack charged groups, the water molecules have nothing to stick to and don’t mix with them.

Detailed explanation-3: -Lipids are a diverse group of compounds that are united by a common feature. Lipids are hydrophobic (“water-fearing”), or insoluble in water. Lipids perform many different functions in a cell. Cells store energy for long-term use in the form of lipids called fats.

Detailed explanation-4: -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.
