The portion of the structure of a sphingophospholipids that constitute its head in the “head and two tails” model has to be stated. Concept introduction: In sphingophospholipids, the platform molecule is sphingosine to which one fatty acid and one phosphate group are attached. An alcohol is attached to the phosphate group. There are two ester linkages and one amide linkage present in the structure of sphingophospholipids.
