Possible Interaction: Methionine and Phosphatidylethanolamine

“The results indicated that stepwise methylation of phosphatidylethanolamine with labeled methyl group of methionine was occurring to a minor extent, as was a negligible amount of choline exchange.”

“These results support the idea that the differential effects of dietary proteins on lipid metabolism might be ascribed, at least in part, to their different methionine contents, and that methionine might exert its effects through alteration of PE N-methylation.”

“While there was little effect of choline on the synthesis and amount of cellular phosphatidylethanolamine, the addition of methionine diminished cellular phosphatidylethanolamine levels.”

“The active one-carbon units from methionine and serine appear to be involved in the methylation of phosphatidylethanolamine to form phosphatidylcholine.”
