Citrate Synthase from porcine heart, in ammonium sulfate suspension, is widely used in biochemical research and diagnostic applications. It plays a crucial role in studying the citric acid cycle (Krebs cycle), as it catalyzes the condensation of acetyl-CoA and oxaloacetate to form citrate. This enzyme is often employed in enzymatic assays to measure the activity of other enzymes or metabolites involved in cellular metabolism. It is also utilized in diagnostic kits for assessing mitochondrial function and energy metabolism in clinical and research settings. Additionally, it serves as a tool in metabolic pathway analysis and in vitro studies to understand cellular respiration and energy production mechanisms.
