Pathways of phosphoinositide metabolism. A: Pathways for inter-conversion of phosphoinositides by lipid kinases and phosphatases. Enzyme activities mentioned in the text are highlighted. B: A schematic illustration of the major pathways for de novo synthesis of phosphoinositides in higher eukaryotes. Enzyme activities highlighted indicate points at which enrichment for C38:4 species may occur.
