PEMT stands for Phosphatidylethanolamine N-Methyltransferase. It is an enzyme that converts phosphatidylyethanolamine into phosphatidylycholine in the liver. The gene that codes for this enzyme is found on chromosome 17 in humans and is the site of frequent misspellings (or SNPs) that impact the function of the protein in this very important metabolic process to produce the phospholipid phoshatidylcholine.
