Protein molecules contain dissociable groups such as carboxyl and amino groups. Due to the different structures of different protein molecules, the composition of their ionizing groups and the exposure on the surface of the molecule are different, so the nature and net charge of different protein molecules are charged. Also different.
Different customized plant protein For sale have different solubility. The solubility of protein molecules in water mainly depends on the thickness of the hydration layer on the surface and the number of charges.
