Biochemistry
Oxaloacetate is a four-carbon dicarboxylic acid that plays a critical role in metabolism, primarily as an intermediate in the citric acid cycle. It serves as a key starting point for gluconeogenesis, contributing to glucose synthesis when carbohydrates are scarce, and it is essential for replenishing citric acid cycle intermediates through anaplerotic reactions. Oxaloacetate's regulation and availability influence various metabolic pathways and energy production.
