Glycerol-3-phosphate dehydrogenase shuttle
WebIn the glycerol-phosphate shuttle, glycerol is phosphorylated to glycerol-3-phosphate (G3P) and then dehydrogenated to DHAP by Glycerol-3-phosphate dehydrogenase (G3PDH) in the cytoplasm. G3PDH is the same enzyme which is used for transporting electrons from the cytosolic NADH2 (produced by glycolysis) into the mitochondri- ... WebIt forms a glycerol phosphate shuttle and facilitates the transfer of reduced equivalents across the mitochondria to the cytosol. ... The Glycerol 3-Phosphate Dehydrogenase Activity Colorimetric Assay Kit provides a simple and sensitive procedure for measuring GPDH activity in a variety of tissues and cells. GPDH activity is determined by ...
