Oxaloacetate is a four-carbon dicarboxylic acid that plays a crucial role in the citric acid cycle, also known as the Krebs cycle. It is formed from pyruvate and is essential for the regeneration of citric acid, which drives cellular respiration and energy production. This compound acts as a key intermediary that connects various metabolic pathways, facilitating the conversion of carbohydrates, fats, and proteins into usable energy.
