Citric Acid Cycle Enzymes

Mnemonic to remember the order of the enzymes: "So At Disco, Devil Sipped Down Five Drinks."

Enzyme Details

Citrate Synthase: The first enzyme in the citric acid cycle, catalyzes the synthesis of citrate from acetyl-CoA and oxaloacetate.
Aconitase: The second enzyme, converts citrate into isocitrate through a two-step process involving cis-aconitate.
Isocitrate Dehydrogenase: The third enzyme, oxidizes isocitrate to α-ketoglutarate while reducing NAD+ to NADH and releasing CO2.
α-Ketoglutarate Dehydrogenase: The fourth enzyme, converts α-ketoglutarate to succinyl-CoA, also producing NADH and CO2.
Succinyl-CoA Synthase: The fifth enzyme, catalyzes the conversion of succinyl-CoA to succinate, generating GTP or ATP.
Succinic Dehydrogenase: The sixth enzyme, converts succinate to fumarate, reducing FAD to FADH2 in the process.
Fumarase: The seventh enzyme, facilitates the hydration of fumarate to malate.
Malate Dehydrogenase: The eighth enzyme, converts malate back to oxaloacetate, producing NADH and completing the cycle.
