Fats and phospholipids contain glycerol whereas steroids do not.

Explanation:

Fats and oils are the storage form of lipids while phospholipids and steroids play structural roles in the body.

Fats are the triacylglycerols in which three fatty acids bonded in ester linkage to one glycerol molecule. Here, the three fatty acids can be identical or different from each other. Examples of fats include tristearin, tripalmitin, etc.

Phospholipids are the amphipathic lipids with a polar head and nonpolar tails. Glycerophospholipids are one of the two categories of phospholipids. In glycerophospholipids, one molecule of glycerol is bonded to two fatty acids and one highly polar group such as phosphate alcohol.

On the other hand, steroid lipids consist of characteristic steroid nucleus composed of four fused rings. Here, three rings have six carbon atoms while the fourth ring has only five carbon atoms. Steroids do not have glycerol molecule.
