| Application: | Iodoacetamide has been used: • in protein digestion for proteomic analysis • to alkylate protein samples • in the denaturation of cow′s milk allergens, β-lactoglobulin (BLG) and α-lactalbumin (ALA) |
| Biochem/physiol Actions: | Iodoacetamide (IAA) is used to inhibit glycolysis due to its ability to irreversibly inhibit the glycolytic enzyme glyceraldehyde-3-phosphat |
| Biochem/physiol Actions: | Iodoacetamide acts as an alkylating reagent for cysteine residues in peptide sequencing. It is an irreversible inhibitor of enzymes with cysteine at the active site. It reacts much more slowly with histidine residues, but that activity is responsible for inhibiting ribonuclease. |
