Glycerol phosphate enzyme
Glycerol-3-phosphate dehydrogenase (GPDH)
Also searched as Glycerol-3-phosphate dehydrogenase (GPDH).
Rebuilding fat needs a three-carbon scaffold, and this enzyme makes it. Blocking it starves the rebuilding step. It also explains something important about how fat release is measured: the standard test reads free glycerol in the fluid around the cell. If this enzyme is blocked, glycerol is not used up rebuilding fat, so it accumulates — and a higher reading can mean more fat coming out OR less being put back. On the readout those look the same. One entry here blocks this enzyme almost completely, which is useful in itself, and means its own release figure should be read with that in mind.
In depth
The enzyme that builds the scaffold released fat is re-attached to — and the reason one common measurement can mislead.
What drives it
Blocks new fat cells increases it.
Glycerol-3-phosphate dehydrogenase is the canonical PPARgamma-driven adipocyte differentiation marker enzyme. PMID 27638500
What it drives
It increases Glycerol backbone.
The enzyme that builds the backbone fat is rebuilt on — and the reason one measurement in this field can mislead. 'GPDH is an important enzyme for lipid metabolism that is central to triglyceride synthesis' and has an 'important role... In converting preadipocytes to adipocytes' (doi 10.3390/molecules191216656 (pmc6270905) — Anti-Obesity Effects of Hispidin and Alpinia zerumbet Bioactives in 3T3-L1 Adipocytes). It makes the three-carbon scaffold onto which released fatty acids are re-attached. Here is why it matters for reading any fat-release number: the standard test measures free glycerol in the fluid around the cell. If this enzyme is blocked, glycerol is not consumed to rebuild fat — so it accumulates. A rise in the measurement can therefore mean more fat coming out, OR less being put back, and the two look identical on the readout. One compound in this formula inhibits it by nearly ninety-eight percent, which is genuinely useful — and means its headline release figure must be read with that in mind rather than at face value. doi 10.3390/molecules191216656
It increases Fat re-storage.
