GENERAL KNOWLEDGE

Detailed explanation-1: -Lipids are a class of macromolecules that are nonpolar and hydrophobic in nature. Major types include fats and oils, waxes, phospholipids, and steroids. Fats are a stored form of energy and are also known as triacylglycerols or triglycerides. Fats are made up of fatty acids and either glycerol or sphingosine.

Detailed explanation-2: -Nonglyceride lipids (sphingolipids, steroids, waxes)

Detailed explanation-3: -Hydrolysable and Non-hydrolysable Lipids These include neutral fats, waxes, phospholipids, and glycolipids. Fats and oils are composed of triglycerides, made up of glycerol (1, 2, 3-trihydroxypropane) and 3 fatty acids to form a triester. Triglycerides are found in the blood, and stored in fat cells.

Detailed explanation-4: -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.
