Resumo
The biochemical function of metal ions in many processes is of fundamental importance, both in the
human body and in optoelectronic devices. Most metal cations in living organisms interact with proteins,
and therefore the study of metal-protein binding sites has attracted much attention in scientific research.
Amino acids, which contain proton-donating groups (carboxylic acid, -COO) and proton-accepting
groups (amino, -NH2), are fascinating organic materials for applications in semi-organic nonlinear
optical (NLO) crystals. Single crystals of amino acids complexed with transition metals exhibit several
important physical properties, such as optical (especially nonlinear optics), piezoelectric, and
ferroelectric properties. These studies also contribute to the understanding of neurodegenerative
diseases, such as Parkinson's, Alzheimer's and Creutzfeldt-Jakob Disease. The zwitterionic
characteristic of amino acid molecules facilitates the manipulation of this substance. In this context, the
present study was dedicated to the characterization, by X-ray diffraction as a function of temperature
and Raman Spectroscopy, of pure and complexed crystals of Nickel L-Histidinate, Nickel L-Alaninate
and Copper D-Alaninate, grown by the method of slow evaporation of an aqueous solution, with the
aim of enriching studies in this field.
