Pyruvate vs. Pyruvic Acid: What's the Difference?
Pyruvate is the ionized form of pyruvic acid, a key intermediate in several metabolic pathways; pyruvic acid is its undissociated, protonated form.
Pyruvate, the conjugate base of pyruvic acid, exists predominantly at physiological pH. Pyruvic acid is the protonated form, with an additional hydrogen ion.
Pyruvate is a critical energy currency in cellular metabolism, often produced by glycolysis. Pyruvic acid, while chemically similar, is less commonly referenced in biological systems due to its protonated state.
In solution, pyruvate readily accepts a proton to become pyruvic acid, especially in acidic conditions. Pyruvic acid, under more alkaline conditions, loses a proton to form pyruvate.
Pyruvate is often used in research and laboratory settings to study metabolic pathways. Pyruvic acid, though similar, is more often referenced in the context of its chemical properties.
In the body, pyruvate serves as a key link between different metabolic processes. Pyruvic acid, by contrast, is less commonly encountered but is important in understanding the chemistry of pyruvate.
