Citric acid, also known as citrate, is formed in the Krebs cycle (also known as the citric acid cycle or TCA cycle) through the condensation of acetyl-CoA and oxaloacetate.

Citric acid, which people also call citrate, is made in a process called the Krebs cycle (or sometimes the citric acid cycle or TCA cycle). This happens when a molecule called acetyl-CoA combines with another molecule called oxaloacetate. This is an important step in how our bodies break down food for energy!
