WebNADPH is an electron carrier that is produced in the cell by a number of different metabolic pathways, such as the malate-aspartate shuttle and the pentose phosphate pathway. The reduction of NADPH to NADP+ during fatty acid desaturation supplies the reducing equivalents essential for the insertion of double bonds into the fatty acid chain. WebNote: The malate-aspartate shuttle transports NADH into the mitochondria from the cytoplasm. The alternative to this is the glycerol phosphate shuttle, which is less …
