What is Isocitric acid?

Isocitric acid, also known as isocitrate, is a key intermediate in the tricarboxylic acid (TCA) cycle, a central pathway for energy generation in eukaryotic cells. It is an isomer of citric acid and serves as a critical substrate for enzymes such as isocitrate dehydrogenase (IDH), which is involved in the oxidative decarboxylation of isocitric acid to α-ketoglutarate. Understanding the metabolism of isocitric acid is vital for unraveling the intricacies of cellular respiration and energy production.

Analyzing isocitric acid is crucial as it provides valuable insights into cellular energy production, serves as biomarkers for various metabolic diseases and cancer, and supports drug development. It aids in comprehending energy efficiency, early disease detection, and drug efficacy assessment.

Isocitric Acid Metabolism

Isocitric Acid is metabolized through a series of enzymatic reactions, ultimately leading to the production of ATP and reduced coenzymes such as NADH and FADH2. The metabolism of Isocitric Acid involves the following steps:

  • Conversion to α-Ketoglutarate: Isocitric Acid is first decarboxylated to α-ketoglutarate by Isocitrate Dehydrogenase (IDH).
  • Generation of NADH: During the conversion, NADH is produced, which is essential for oxidative phosphorylation.
  • Subsequent TCA Cycle Reactions: α-Ketoglutarate enters the TCA cycle, where it undergoes further oxidation reactions to produce ATP.
