Question
Chapter 19, Problem 19.59E
Interpretation Introduction
Interpretation:
The information that is obtained about the polypeptide’s isoelectric point is to be stated.
Concept introduction:
The effect that is observed in a cloudy solution of suspension of insoluble particles by passing a beam of light through it, which causes the scattering of light, is known as Tyndall effect. This scattering of light is totally dependent upon the particle’s density and light’s frequency.
