Fat Synthesis and Its Regulation in PlantsⅨ.The Regulatory Action of the Oxidation Rate of NADPH 2 in the HMP Pathway and Fat Synthesis in Rape Seeds[1]

Studies were made on the action of artificial electron acceptors（PMS，MB，TPTZ）on the production of C14O2 by developing rape seed incubated with glucose labelled at carbon 1 and carbon 6.Observations were made on the rate of oxidation of glucose C-1 and C-6 during stimulated fat synthesis.

Results showed that all the three artificial electron acceptors have biological activity.They all can accept electron from NADPH2 and enhance transfer.They all stimulate respiration，by acting in the HMP pathway，though differ in certain aspects.Arsenite can also stimulate fat synthesis and concurrently C14O2 production from C-1 labelled glucose.(https://www.daowen.com)

The results supply additional evidence to the interrelationship between fat formation and the HMP pathway.
