Detailed explanation-1: -Final answer: Lipids are insoluble in water because lipid molecules are hydrophobic.

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: -Hydrophobic means that lipids detest water. They are insoluble in water. Water cannot bind to a lipid molecule because lipids are non-polar molecules while water is polar. Oils and fats create droplets on the surface of the water because non-polar lipids will attach to themselves instead of to one another.
