Usage and Biology
Arginine (R) is a basic amino acid with the presence of a guanidino group at its aliphatic side chain. It is typically protonated at physiological pH where the guanidino group turns into a cationic guanidinium moiety that is highly stable and able to self-associate and cluster. These properties contribute to the intra- and intermolecular associations of arginine residues, as it provides a great capacity for electrostatic interactions (especially hydrogen-bonding) that results in a tendency to form stable clusters in solution.
Arginine has long been recognized as a chemical chaperone, with its ability to interact with and influence proteins in solution. In silico experiments have proved its ability to bind protein surfaces for a long time through its carboxyl and guanidinium groups, and form clusters through self-association with other arginine molecules. This has led to various in vitro experiments that proved the ability of arginine to suppress protein aggregations, which made it a very interesting candidate in the modulation of proteopathies correlated with Alzheimer’s disease.
