Study of ternary complexes involving auxins and amino acids with side groups

Abstract

Stability constants of mixed ligands complexes [MAIL,] (where M = Cu 2 +, Ni 2 +, Zn 2 +, A = indole acetic acid, (IAA) indole propionic acid (IPA) and indole butyric acid (IBA); L = a-alanine, phenylalanine, tyrosine and tryptophan) were determined using the SCOGS computer program. The stabilization of ternary complexes has been attributed to intramoleeular interactions between the two ligands.
