PEMT (Phosphatidylethanolamine N-Methyltransferase): PEMT catalyzes the conversion of phosphatidylethanolamine to phosphatidylcholine in the liver, an essential process for maintaining cell membrane integrity and VLDL secretion. PEMT's activity influences liver health, fat metabolism, and choline requirements. Dysregulation of PEMT is linked to liver and cardiovascular diseases, highlighting its significance in metabolic health....
