Anhydrous Proton Conduction of Soy Protein

International Journal of Electrochemical Science, 2021
Water-soluble soy protein contains a large amount of acidic amino acids, such as glutamic and aspartic acids. Since these acidic amino acids possess the –COOH group in their side chain, the water soluble soy protein acts as an acidic polymer.
