Disease Roles
Acid-Base Balance via Bicarbonate Generation from Acetate Overview
The process of acid-base balance achieved through the metabolism of acetate, typically administered as sodium acetate, to generate bicarbonate ions. This mechanism is crucial in clinical settings for correcting metabolic acidosis, particularly in dialysis and parenteral nutrition, by providing a buffering effect and raising blood pH. It relies on cellular metabolism to convert acetate into bicarbonate, offering a slower but potentially safer alternative to direct bicarbonate administration.
Mechanism of Action
Acetate is metabolized to acetyl-CoA, which enters the citric acid cycle, producing CO2. CO2 is then converted to bicarbonate via carbonic anhydrase, increasing blood pH.
