Which nutrient plays a role in cell membrane production and fatty acid metabolism?

The nutrient that plays a crucial role in cell membrane production and fatty acid metabolism is choline. Choline is a water-soluble nutrient that is involved in the synthesis of phosphatidylcholine, a major component of cell membranes. It contributes to the structural integrity of cell membranes and is essential for the formation of lipoproteins.

Choline also plays a significant role in fatty acid metabolism, particularly in the export of fat from the liver. It is necessary for the production of very low-density lipoproteins (VLDL) that transport triglycerides and cholesterol out of the liver to other tissues, preventing the accumulation of fat in liver cells.

In contrast, the other options, while relevant in different metabolic contexts within the body, do not specifically correspond to the roles that choline plays in membrane production and fatty acid metabolism. For instance, 11C-Acetate is mainly involved in energy production through the Krebs cycle but does not directly influence cell membrane synthesis. FDG (Fluorodeoxyglucose) is primarily used in PET imaging to assess glucose metabolism but does not have a role in fatty acid metabolism or membrane production. Meanwhile, 11C-Glutamine is linked to amino acid metabolism and nitrogen transport but does not
