Oxaloacetic Acid is a four-carbon dicarboxylic acid often abbreviated as OAA. It is involved in many metabolic processes, including the Krebs cycle and gluconeogenesis. Some synonyms for oxaloacetic acid include acetylfuroxan, pyruvic acid, glyoxylic acid, and keto-oxo acid. However, it should be noted that these compounds are not identical to OAA and can have different chemical properties and functions. For example, pyruvic acid is a three-carbon compound, while glyoxylic acid is an aldehyde and not a carboxylic acid. Understanding the synonyms and related compounds to OAA can provide insight into its broader role in cellular function and metabolism.
