Overview

Proteins and amino acids are the nitrogen-containing macromolecules and their building blocks that perform much of the structural and functional work of the body. Amino acids, joined by peptide bonds, fold into proteins that act as enzymes, structural elements, transporters, hormones, and immune molecules, and they also serve individually as metabolic intermediates, neurotransmitter precursors, and signalling molecules. Of the twenty proteinogenic amino acids, several are indispensable in the human diet, while others are conditionally essential under stress or disease; protein quality is judged by amino-acid composition and digestibility. Beyond their nutritional role, amino acids participate in nitrogen metabolism, gluconeogenesis, and the synthesis of specialized compounds, and their analysis is fundamental to biochemistry and food science. Peer-reviewed research relevant to this area examines the role of amino acids and their derivatives in the pathogenesis and treatment of liver disease, the metabolomic profiling of amino acids in biological systems, the analytical determination of amino acids, peptide synthesis and side-chain protection, and the protein and amino-acid composition of plant foods and nutritional supplements. Studies span analytical chemistry, metabolomics, clinical investigation, and food-composition analysis. This work connects the chemistry and metabolism of amino acids and proteins to physiology and nutrition. The journal publishes peer-reviewed research addressing nutrition and the biochemistry of proteins and amino acids.
