Question 25

What is the purpose of acetate and gluconate in fluids?

Answer 25

The acetate is oxidized by the liver, muscle, and heart into bicarbonate, with a small percentage converted to acetoacetate. The gluconate is converted to glucose, which can then be used as a substrate for glycolysis and citric acid cycle.
