reported an increased level of PI and decreased level of PE in cells upon depletion of zinc.8b The activities of most enzymes in the CDP‐diacylglycerol pathway, including phosphatidylserine synthase and decarboxylase, appear to be decreased in response to zinc deficiency and thus, this condition results in a decreased PE level.18 In contrast, by upregulating the activity of PI synthase, zinc deficiency elevates the level of PI. This evidence concerns the gene CDIPT and Zinc deficiency.
