Choline functional group
WebCholine has several important functions. It is a constituent of an important class of lipids (fats) called phospholipids ( e.g., lecithin), which form structural elements of cell … WebDuring the reaction the hydroxyl group of the carboxylic acid is converted to a chlorosulfite intermediate making it a better leaving group. The chloride anion produced during the reaction acts a nucleophile. Example Mechanism 1) Nucleophilic attack on Thionyl Chloride 2) Removal of Cl leaving group 3) Nucleophilic attack on the carbonyl
