  Enzymatic transformation of glyceroglycolipids into sn-1 and sn-2 lysoglyceroglycolipids by use of Rhizopus arrhizus lipase

  摘要：

  Lipase from Rhizopus arrhizus catalyzed deacylation of two classes of glyceroglycolipids, monogalactosyl diacylglycerol(MGDG), and digalactosyl diacylglycerol(DGDG), proceeded regiospecifically to furnish sn-1 lysoglyceroglycolipids quantitatively. The lipase also catalyzed complete acyl migration of sn-1 lysoglycerogalacto-lipids leading to sn-2 lysoglycerogalactolipids.
