  2. Oxaloacetic acid - Wikipedia

    en.wikipedia.org/wiki/Oxaloacetic_acid

    Oxaloacetic acid (also known as oxalacetic acid or OAA) is a crystalline organic compound with the chemical formula HO 2 CC(O)CH 2 CO 2 H. Oxaloacetic acid, in the form of its conjugate base oxaloacetate, is a metabolic intermediate in many processes that occur in animals.

  3. Keto acid - Wikipedia

    en.wikipedia.org/wiki/Keto_acid

    pyruvic acid, pervasive intermediate in metabolism. oxaloacetic acid, a component of the Krebs cycle. [5] alpha-ketoglutaric acid, a 5-carbon ketoacid derived from glutamic acid. Alpha-ketoglutarate participates in cell signaling by functioning as a coenzyme. [6] It is commonly used in transamination reactions.

  4. Pyruvate carboxylase - Wikipedia

    en.wikipedia.org/wiki/Pyruvate_carboxylase

    The reaction it catalyzes is: pyruvate + HCO − 3 + ATP → oxaloacetate + ADP + P. It is an important anaplerotic reaction that creates oxaloacetate from pyruvate. PC contains a biotin prosthetic group [1] and is typically localized to the mitochondria in eukaryotes with exceptions to some fungal species such as Aspergillus nidulans which have a cytosolic PC.

    en.wikipedia.org/wiki/Talk:Oxaloacetic_acid

    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 ?

  6. C4 carbon fixation - Wikipedia

    en.wikipedia.org/wiki/C4_carbon_fixation

    CO 2 is initially fixed in the mesophyll cells in a reaction catalysed by the enzyme PEP carboxylase in which the three-carbon phosphoenolpyruvate (PEP) reacts with CO 2 to form the four-carbon oxaloacetic acid (OAA). OAA can then be reduced to malate or transaminated to aspartate.

  7. GOT1 - Wikipedia

    en.wikipedia.org/wiki/GOT1

    Glutamic-oxaloacetic transaminase is a pyridoxal phosphate-dependent enzyme which exists in cytoplasmic and mitochondrial forms, GOT1 and GOT2, respectively. GOT plays a role in amino acid metabolism and the urea and tricarboxylic acid cycles. The two enzymes are homodimeric and show close homology. [6]

  8. Malate dehydrogenase - Wikipedia

    en.wikipedia.org/wiki/Malate_dehydrogenase

    Malate dehydrogenase (EC 1.1.1.37) (MDH) is an enzyme that reversibly catalyzes the oxidation of malate to oxaloacetate using the reduction of NAD + to NADH. This reaction is part of many metabolic pathways, including the citric acid cycle.
