Lipids are a broad group of compounds from biological origin that can dissolve in nonpolar solvents, such as chloroform and diethyl ether

Even though they are different in structure (diff. types- fats,w­axe­s,s­ter­ols­,fa­t-s­oluble vitamins A D E K), they share some same properties

Energy storage

Buoyancy

Free fatty acid

Choles­terol ester

glycogen used for short-term energy storage, they converted to glucose when energy is required.

Lipids have more energy content per unit mass of carboh­ydrates

Trigly­cer­ide­s(甘油三酯) converted to fatty acids and glycerol → energy
