Oxaloacetate synthesized from which amino acid -: (A) Aspartate, (B) Glycine, (C) Serine, (D) Valine
Answer is A. 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
