Mitochondria
Oxaloacetate is converted into Malate or Phosphoenolpyruvate before it leaves the mitochondria, does that mean it cannot leave in oxaloacetate form?

Interconversion picture
The picture is misleading because it does not relate to any biological process - at pH7, carboxylic acids are deprotonated - dehydrogenation does not produce free H2, it is coupled to reduction of NAD+ - similarly, NH3 is not released as free ammonia, as shown - etc —Preceding unsigned comment added by 90.242.88.79 (talk) 16:32, 23 September 2007 (UTC)

Enol form(s)
Properties section says "The enol forms of oxaloacetic acid are particularly stable, so much so that the two tautomer have different melting points (152 °C for the cis isoform and 184 °C for the trans isoform)." Does this mean the structure shown is the keto form and that there are two enol (iso)forms ? A diagram of at least one of the enol isoforms would be helpful ? - Rod57 (talk) 05:48, 29 March 2016 (UTC)
