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: -What is a lipid? A lipid is any of various organic compounds that are insoluble in water. They include fats, waxes, oils, hormones, and certain components of membranes and function as energy-storage molecules and chemical messengers.

Detailed explanation-3: -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-4: -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-5: -Lipids are fatty, waxy, or oily compounds that are soluble in organic solvents and insoluble in polar solvents such as water. Lipids include: Fats and oils (triglycerides)
