Question

which is an example of a lipid?
cholesterol
glycerol
glycogen
proteins

Explanation:

Lipids are a diverse group of organic compounds that are insoluble in water but soluble in non - polar solvents. Cholesterol is a type of lipid known as a steroid. Glycerol is a component of some lipids (like triglycerides, where it combines with fatty acids), but on its own, it is not typically considered a lipid in the same sense as cholesterol. Glycogen is a polysaccharide (a type of carbohydrate) used for energy storage in animals. Proteins are a completely different class of macromolecules with their own structure and function, separate from lipids.
