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.

What type of step is this? Check all that apply.
Draw the products of the step on the right-hand side of the drawing area
below. If more than one set of products is possible, draw any set.
Also, draw the mechanism arrows on the left-hand side of the drawing
area to show how this happens.
