Detailed explanation-1: -Lipids are compounds that are insoluble in water but are soluble in organic solvents such as ether and chloroform. Lipids that are important to our discussion include fats and oils (triglycerides or triacyglycerols), fatty acids, phospholipids, and cholesterol.
Detailed explanation-2: -Answer and Explanation: A molecule that is insoluble in water is called hydrophobic. Fats and steroids are examples of hydrophobic molecules that are insoluble in water. In contrast, a molecule that is soluble in water is called hydrophilic.
Detailed explanation-3: -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.
