Question: what is the structural difference between glycerophospholipids and sphingomyelins?
Answer: Glycerophospholipids are made by combining glycerol, two fatty acids, one phosphate group, and one organic group. Sphingolipids contain the alcohol sphingosine and contain a phosphate attached to both sphingosine and an organic group. Glycolipids are lipids that contain a sugar residue.
