CAS 328-42-7

Oxaloacetic acid

Description:

Oxaloacetic acid, with the CAS number 328-42-7, is a four-carbon dicarboxylic acid that plays a crucial role in various metabolic pathways, particularly in the citric acid cycle (Krebs cycle). It is a colorless, crystalline solid that is soluble in water and has a slightly acidic nature due to the presence of two carboxyl (-COOH) groups. The molecular formula of oxaloacetic acid is C4H4O5, and it exists in equilibrium with its anionic form, oxaloacetate, at physiological pH. This compound is essential for the synthesis of amino acids and is involved in gluconeogenesis, the process of generating glucose from non-carbohydrate substrates. Oxaloacetic acid can also participate in transamination reactions, contributing to the formation of aspartate. Its reactivity is characterized by the ability to undergo decarboxylation and condensation reactions, making it a versatile intermediate in organic synthesis and biochemistry. Due to its biological significance, oxaloacetic acid is of interest in research related to metabolism, energy production, and various diseases.

Oxalacetic acid

CAS: 328-42-7

Oxalacetic acid is a metabolite of oxaloacetate, which is produced by the decarboxylation of oxalacetic acid. It is a precursor in the citric acid cycle. Oxalacetic acid has been shown to be found in high concentrations in cancer tissues and plant leaves, where it functions as part of the citric acid cycle. Oxalacetic acid binds metal ions such as copper, zinc and iron with high affinity, forming metal chelates. Oxalacetic acid has also been found to inhibit proliferation of HL-60 cells.

Oxalacetic acid

CAS: 328-42-7

Oxalacetic acid is an essential component of the Krebs cycle where it combines with acetyl-coenzyme A to yield citric acid. Thus, it is a necessary intermediate in the intercyclicpathway between the Embden-Meyerhof cycle and the Krebs cycle. The prime function of these cycles is the production of energy and the shunting out of these acids effectively slowsthe cycle down. Therefore, keto acids, such as pyruvate andoxalacetic, are frequently added to tissue culture media formulations to maintain maximum cell metabolism.
