Verified step by step guidance

Understand the structure of phosphatidate: It is a glycerophospholipid, which means it is composed of a glycerol backbone, two fatty acid chains, and a phosphate group.

Identify the components needed to form phosphatidate: The glycerol backbone is provided by glycerol-3-phosphate, and the two fatty acid chains are attached to this backbone.

Consider the biochemical pathway: Glycerol-3-phosphate is a common intermediate in lipid metabolism, and it can be acylated by two fatty acids to form phosphatidate.

Evaluate the options: Option (a) 'Glycerol-3-phosphate and two fatty acid chains' correctly describes the formation of phosphatidate, as it involves the acylation of glycerol-3-phosphate with two fatty acids.

Eliminate incorrect options: Options (b), (c), and (d) do not accurately describe the formation of phosphatidate, as they either involve incorrect substrates or do not align with the known biochemical pathway.
