Protein amphoteric
Webb25 feb. 2009 · Use of amphoteric and anionic surfactants is very common in practical formulations such as shampoos and hand dishwashing products. Precipitation of mixtures of dimethyldodecylamine oxide (DDAO) as an amphoteric surfactant and sodium dodecyl sulfate (SDS) as an anionic surfactant were studied at different pH levels. WebbProteins are made up of many amino acid molecules all bonded together by peptide bonds. Therefore proteins are also known as polypeptides. ... Due to the amino and carboxyl groups, amino acids are amphoteric which means that …

Amphoteric molecules, such as proteins, can bind to both anionic and cationic exchangers. The net charge of a protein changes as a function of pH. Below the isoelectric point, the molecule has a net positive charge and would bind to a cation exchanger.
