TARGETING PROTEINS
Chlorine dioxide (ClO2) is highly reactive with thiols, phenols, secondary amines and tertiary amines. Therefore, proteins composed of amino acids which present these
reactive groups are vulnerable to oxidation by this agent. Proteins which present residue(s) of the amino acid L-cysteine are discussed above under TARGETING THIOLS. L-tyrosine presents a phenol group and is therefore similarly vulnerable. L-tryptophan and L-histidine present secondary amino groups which are also especially reactive with chlorine dioxide.
