<prompt> Oxaloacetate synthesized from which amino acid -AspartateGlycineSerineValine  <response>: Ans. is a i.e., Aspartate Oxaloacetate, an intermediate in citric acid cycle is formed from Aspartate and Asparagine Aspartate undergoes transamination in the presence of Aspartate Transaminase AST or Serum Glutamate Oxaloacetate Transaminase SGOT Aspartate a Ketoglutarate---Oxaloacetate Glutamate AST SGOT Asparagine in the presence of Asparaginase, gets converted to Asparate. Aspartate is then converted to OxaloacetateAsparagine---Aspartate NH3 ASPARAGINASE
