1. All alpha-amino acids are oxidized by periodate, but at different rates. 2. The rates of oxidation of individual alpha-amino acids vary with pH. In general, oxidation proceeds more rapidly at alkaline pH. 3. Serine, threonine, cysteine, cystine, methionine, proline, hydroxyproline, tryptophan, tyrosine and histidine are rapidly and extensively oxidized by periodate. 4. Cysteine, cystine, methionine, tryptophan, tyrosine and histidine are oxidized by periodate when they are substituted in the carboxyl and amino groups, as in a polypeptide chain.
