Oxamic acid is an organic compound with the formula NH2C(O)COOH. It is a white, water-soluble solid. It is the monoamide of oxalic acid.[3] Oxamic acid inhibits lactate dehydrogenase A.[4] The active site of lactate dehydrogenase (LDH) is closed off once oxamic acid attaches to the LDH-NADH complex, effectively inhibiting it.[5]
Oxamic acid also has applications in polymer chemistry. It increases the water solubility of certain polymers, including polyester, epoxide, and acrylic upon binding with them.[6]
