L-Tryptophan Aqueous Systems at Low Concentrations: Interconnection between Self-Organization, Fluorescent and Physicochemical Properties, and Action on Hydrobionts.

As shown by fluorescence monitoring of dissolved organic matter, amino acid -Trp can be present in natural water. The consequences of the presence of -Trp at low concentrations in surface water systems are not yet established for hydrobionts. Studying the physicochemical patterns, as well as their relationships to the bioeffects of -Trp solutions in the low concentration range, can provide new and important information regarding the unknown effects of -Trp.
