Micronutrient Complexation with Amino Acid: Electrochemical, Bioanalytical and Thermodynamic Data

Abstract

Electrochemical behaviour of several amino acids viz., glycine, lysine,valine, alanine etc. and their complexation with micronutrients viz., Cu²⁺,Co²⁺, Zn²⁺ and Fe³⁺ in binary and mixed system could be estimatedalongwith thermodynamic parameters ΔG, ΔH, ΔS. Dissociation constantswere determined employing Albert and Serjeant, Noyes and Irving-Rossottitechniques. Free amino acids take part in numerous metabolic reactions.Mechanistic studies in amino acids are an effort to correlate the dataobtained from electrochemical, bioanalytical and thermodynamic studies.The validity of the mechanism is tested on the basis of recalculation, TLC,formation constant, higher sensitive polarographic methods and availablebioanalytical procedures.
