V. De novo Synthesis of Fatty Acids Acetyl Groups and Reducing Equivalents. Our results reveal that FASN-driven de novo FA synthesis in SCs is mandatory for myelination and identify lipogenic activation of the PPARγ transcriptional network as a putative downstream functional mediator. Nadra K, Médard JJ, Quignodon L, Verheijen MH, Desvergne B, Chrast R. J Neurochem. Thus, de novo lipogenesis is the synthesis of fatty acids, beginning with acetyl-CoA.
