Although arginine chloride is widely used, only few studies have been done with other salt forms.

We examined the effects of six different acids on solubilization of aromatic compounds and unfolded protein by arginine.

Anions affect solubilization of propyl gallate by arginine.

Anions also affect the propyl gallate solubility similarly for sodium and guanidine salts.

Protein solubility and refolding are also affected by anions.
