Answer:
Sphingomyelin and glycolipids are precursors of ceramide.
Glycolipids are sugar molecule(s) attached to a membrane lipid.
Ceramide can be made into either sphingomyelin or a glycolipid depending on what enzyme encounters ceramide first.
Sphingomyelin is a phospholipid made in the Golgi.
Explanation:
Simple sphingolipids are the ceramides. Glycolipids, a large group of sphingolipids, contain one or more molecules of sugar (glucose or galactose).
Lipids that are synthesized in the ER (not in the RER) are cholesterol and ceramide which is further converted to either glycolipids or sphingomyelin in the golgi apparatus. Ceramide can then get sent to the Golgi, where it can be converted into either glycolipids or the only non-glycerol-based phospholipid, sphingomyelin.
SER (not RER) is involved in the synthesis of lipids, including cholesterol and phospholipids, which are used in the production of new cellular membrane.
