Is it hydrophobic or hydrophilic? Lactates can be monitored by low UV, ELSD or LC/MS. Because of its high polarity, lactic acid is immiscible with non‐polar organic solvents, which have generally been used for non‐aqueous enzyme reactions. LDH catalyzes the conversion of lactate to pyruvate and back, as it converts NAD + to NADH and back. Polar molecules must contain polar bonds due to a difference in electronegativity between the bonded atoms.
