Which of the Following is Correctly Defined

Question

Which of the following is correctly defined?
A)sphingomyelin: ceramide + choline
B)glycoglycerolipid: glycerol + fatty acid + monosaccharide + phosphate
C)cerebroside: ceramide + monosaccharide
D)ganglioside: sphingomyelin + oligosaccharide
E)none of the above

Accepted Answer

Cerebroside is correctly defined as ceramide + monosaccharide. Sphingomyelin is composed of ceramide and phosphocholine, not choline, so A is incorrect. Glycoglycerolipid includes a monosaccharide but not a phosphate group, so B is incorrect. Ganglioside contains oligosaccharides in addition to ceramide, not sphingomyelin, so D is incorrect. Therefore, the correct option is C.
