Quizplus · Accepted Answer

Statement (1) is false because steroids have a fused four-ring system, not three. Statement (2) is true as both glycerophospholipids and sphingophospholipids have a "head-and-two-tails" structure. Statement (3) is true because both fats and oils are mixtures of triacylglycerols (TAGs).
