Biochem/physiol Actions
Iodoacetic acid (IAA) blocks the thiol group of cysteine. IAA inhibits glyceraldehyde-3-phosphate dehydrogenase (G3PDH) by interacting with sulfhydryl group of the active site cysteine. IAA inhibits the progression of solid Ehrlich carcinoma. IAA is one of the iodinated disinfection byproducts in drinking water. It is cytotoxic to mammalian cells.
