| oxaloacetate |
Oxaloacetic acid, also known as oxosuccinic acid, is a four-carbon dicarboxylic acid appearing as an intermediate of the citric acid cycle. In vivo, oxaloacetate (the ionised form of oxaloacetic acid) is formed by the oxidation of L-malate, catalysed by malate dehydrogenase, and reacts with Acetyl-CoA to form citrate, catalysed by citrate synthase. It is also formed in the mesophyll of plants by the condensation of CO2 with phosphoenolpyruvate, catalysed by oxaloacetate decarboxylase. ...

| oxidation number |
The oxidation state or oxidation number is defined as the sum of negative and positive charges in an atom, which indirectly indicates the number of electrons it has accepted or donated. The oxidation number is a convenient conceptual approximation when working with complex electrochemical reactions that eases the tracking of electrons and helps verify that they have been conserved. ...
