solutions containing different concentrations of oxaloacetat

Did you see some real peaks with the oxaloacetate and malate or was it rather shifted baseline? (especially in the case of 1:10 dilution) As you can see, the absorbance of oxaloacetate and malate in range 4 - 0.8 mM is rather low if any. On ...

Please help!

1. Sorry, I intended to type Oxaloacetate, not "Ox.-Aloacetate". 2. Sorry, I mistyped that, obviously succinic acid is C4H6O4. 3. Yes, succinate does pass electrons to Coenzyme Q (Q to QH2) but I thought you were referring to ...

Please help!

1) Oxaloacetate is a compound (C4O5) in the tricarboxylic acid cycle, it is an isomer of Malate, after the action of Malate Dehydrogenase or Pyruvate Carboxylase, and is a compund which has been formed (sometimes oxaloacetate, ...
