摘要：

As a primary building block for protein synthesis, L-arginine (L-Arg) is also a precursor for the synthesis of important metabolites, and is involved in various physiological and pathophysiological processes. L-Arg is a potential biomarker in clinical diagnosis and nutritional status assessment, making it valuable to quantify and monitor this biomolecule. In this study, peptide aptamers that specifically interact with L-Arg were identified by high-throughput molecular docking, and the binding capacities between the synthesized peptide aptamers and L-Arg were then measured by isothermal titrati...
