Publisher SummaryAmino acids are organic compounds that contain in their molecule the functional groups NH2 and COOH. The two groups can be attached to the same carbon atom (in α-amino acids) to vicinal carbons (in β-amino acids) etc. Certain α-amino acids represent the building blocks of peptides and proteins, which are polymeric materials formed by water elimination between α-amino acid molecules. The chapter describes the pyrolysis of amino acids such as α, β, γ, etc. A special group of compounds containing carboxyl and amino groups in their molecules is formed by ethylenediaminetetraacetic acid (EDTA) and related compounds. These compounds are strong chelating agents and are used to form stable combinations with many metals. Thermal decomposition of the chelating agents itself is not of high interest but the decomposition of their combinations with some metals has been studied in relation to the preparation of superconducting materials, nanoparticles, and metal oxides films. Peptides are short polymers formed by water elimination between α-amino acid molecules. The resulting amide bond (peptide bond) is formed between the carboxyl group of one amino acid and the amino group of another amino acid. The chapter describes the pyrolysis of small peptides made from a few amino acids.
