Glycerophosphate
Description
Glycerophosphate (synonym: α-glycerophosphate; glycerol-3-phosphate; C3H9O6P) is an organophosphate and it is a component of glycerophospholipids. The mitochondrial Glycerophosphate dehydrogenase complex oxidizes glycerophosphate to dihydroxyacetone phosphate and feeds electrons directly to ubiquinone.
Abbreviation: Gp
MitoPedia topics: Substrate and metabolite
Nomenclature
- Due to an ambiguity in the D,L nomenclature based on the Fisher projection the biologically active enantiomer can be labeled either D-glycerol 1-phosphate or L-glycerol 3-phosphate. Alternatives are sn-glycerol 3-phosphate or DL-alpha-glycerophosphate. Following the Cahn–Ingold–Prelog priority rules, the biologically active substance is always the (R) enantiomer, independent of whether the substance is called glycerol 1-phosphate or glycerol 3-phosphate.

- Recommendation by Chuck Hoppel, Director, Ctr Mitochondrial Diseases; Professor, Dept Pharmacology, Case Western Reserve Univ, Cleveland, Ohio - US OH Cleveland Hoppel CL:
- We tested also Gp: Glycerol 3-phosphate sn-Glycerol 3-phosphate bis(cyclohexylammonium) salt; Sigma G7886, store at -20 °C; FW = 370.42, ≥93.0% (TLC) and obtained similar results.
Application in HRR
- Gp: Glycerol 3-phosphate sn-Glycerol 3-phosphate bis(cyclohexylammonium) salt; Sigma G7886, store at -20 °C; FW = 370.42
- Preparation of 1 M stock solution (dissolved in H2O):
- Weigh 370 mg of Gp and dissolve in 1 ml H2O.
- Divide into 0.2 ml portions.
- Store frozen at -20 °C.
- Preparation of 1 M stock solution (dissolved in H2O):
- Oxygraph-2k manual titrations MiPNet09.12 O2k-Titrations
- 1 M stock solution.
- Titration volume: 20 µl using a 50 µl syringe (2 ml O2k-chamber).
- Final concentration in the O2k-Chamber: 10 mM.
- If a racemic mixture (like Sigma G-2138) is replaced by the biologically active enantiomer the amount of substance (measured in moles) usually has to be halved. However, also consider that stated purities may vary, requiring further adjustments.
