Solution(By Examveda Team)

Protein along with some mineral matter is present in Colloidal state.
The colloidal state is a particulate phase, in which the particles range in. size from 1.0 nm to 10 nm, dispersed in a continuous phase, the dispersion medium.
Proteins are complex macromolecules with dynamic conformations. They are charged like colloids, but unlike colloids, charge is heterogeneously distributed on their surfaces.
