Iodoacetic acid sodium salt, also known as sodium iodoacetate, is a chemical compound widely used in biochemistry and laboratory research for its ability to modify cysteine residues in proteins and inhibit cysteine proteases. This compound demonstrates a minor inhibitory effect on specific enzymatic activities in hen plasma. It is characterized by its solubility in water and alcohol, appearing as a white solid. Its role extends to various research applications, such as enzyme studies, protein structure and metabolism analysis, and the exploration of cellular processes including cell signaling and sodium channel functionality. Iodoacetic acid sodium salt′s capacity to bind to enzyme active sites, obstructing their catalytic functions, makes it useful in understanding protein and cellular mechanisms, DNA and RNA synthesis, and gene expression.
