Disruption of TCA cycle may cause health issue


phosph­atase deficiency

pyruvate dehydr­ogenase is always phosph­ory­lated and thus inactive.
Conseq­uently, glucose is processed to lactate rather than acetyl CoA.
This condition results in unremi­tting lactic acidos­is—high blood levels of lactic acid.
. In such an acidic enviro­nment, many tissues malfun­ction, most notably the central nervous system.

Pyruvate Dehydr­ogenase Links Glycolysis to the Citric Acid Cycle
Oxidative decarb­oxy­lation, from pyruvate to acetyl CoA, Mt
The Citric Acid Cycle Oxidizes Two-Carbon Units
8 steps, 3 irreve­rsible steps, 3 NADH, 1 FADH2, 1 ATP, 2 CO2
Entry to the Citric Acid Cycle and Metabolism Through It Are Controlled
PDH, isocitrate dehydr­oge­nase, alpha-­Ket­ogl­utarate dehydr­ogenase
