Question

Identify true statements about the synthesis of various lipids. The glycerophospholipid biosynthetic pathway provides precursors for the synthesis of triacylglycerols. Triacylglycerols are synthesized by adding prostaglandins to a steroid backbone. Glycerophospholipids may be synthesized from diacylglycerols. Triacylglycerols are synthesized by adding fatty acid groups to a glycerol backbone. The triacylglycerol biosynthetic pathway provides the precursors for the synthesis of glycerophospholipids. Arachidonate is a precursor in the synthesis of prostaglandins.

at least one of the choices is incorrect.
