Description

Application

Iodoacetic acid has been used as an alkylating agent for antibody AR37, serum proteins and strawberry proteome samples extracted from different stages of ripened fruit.

Reagent for the modification of cysteine residues in proteins.

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.
