Air and Water Reactions:Slightly soluble in water.
Reactive Group:Salts, Acidic
Reactivity Profile:Acidic salts, such as D(+)-TRYPTOPHAN, are generally soluble in water. The resulting solutions contain moderate concentrations of hydrogen ions and have pH's of less than 7.0. They react as acids to neutralize bases. These neutralizations generate heat, but less or far less than is generated by neutralization of inorganic acids, inorganic oxoacids, and carboxylic acid. They usually do not react as either oxidizing agents or reducing agents but such behavior is not impossible. Many of these compounds catalyze organic reactions.
