Question

Quizplus · Accepted Answer

This statement is true. S-adenosylmethionine (SAM) is a methyl donor molecule that is involved in numerous methylation reactions in the body, including the synthesis of phosphatidylcholine from phosphatidylethanolamine. This reaction is catalyzed by the enzyme phosphatidylethanolamine methyltransferase (PEMT). Phosphatidylcholine is an important component of cell membranes and is involved in numerous biological processes, including signaling and lipid metabolism.
