Tryptophan loss due to oxidation during hydrolysis can be greatly reduced by the inclusion of reducing agents-usually low-molecular-weight thiols–or oxygen-halide scavengers in the acid hydrolysis procedure. Tryptophan is substantially preserved if hydrolysis is performed with strong acids that do not ...
5A). Upon denaturing, the sulfenyl iodide group regained its typical reactivity and instability. This is indicative that the unusual stability of sulfenyl halide is likely conferred by the surrounding protein environment. Sign in to download hi-res image Fig. 5. Preliminary evidences for protein ...

It is possible to use a leaving group other than halide in these reactions; for example, sulfate has been displaced in a synthesis of the β-aminosulfonic acid taurine (Equation (114)) <43JCS4>. The mild reaction conditions tolerate other functionalities such as esters and ketones <64CB2903...
alkyl groups (i.e., having 1 to 6, preferably 1 to 3, carbon atoms) or hydrogen or may together constitute a cyclic hydrocarbon group; may advantageously be reacted with an aliphatic monocarboxylic acid halide or acid anhydride in the presence of the esterification catalyst and a suitable ...
