The structure of sphingolipids contains a) a phosphate group, amide, glycerol, phosphate, and alcohol. b) a phosphate group, glycerol, two fatty acids, and an alcohol molecule. c) a phosphate group, a cyclic carbon ring, and variable numbers of fatty acids. d) a phosphate group, a carbohydrate molecule, an alcohol, and fatty acids.
Homework Answers
Sphingolipids contain amino alcohol core. The amino alcohol core is sphingosine. In addition, a phosphate group and fatty acid residue is also present. Amino group of amino alcohol core forms an amide linkage with fatty acid residue. Hence, option a) is correct answer.

Part A: In glycerophospholipids, 2 fatty acids are added onto glycerol in via ester linkages. Also attached is a phosphate group and an alcohol. Using serine as the alcohol and any 2 fatty acid molecules, draw the structure of a glycerophospholipid. Part B: In sphingophospholipids, 1 fatty acid is added onto glycerol in via an amide linkage. Also attached is a phosphate group and the alcohol choline. Using any 1 fatty acid, phosphate and choline, draw the structure of a...
