Question
Study the given chromatogram, which was obtained for protein extracted from soya milk. Identify the components which are present in the protein?
- Only W and X
- Only W and Y
- Only W, X and Y
- Only W and Z
Hint:
Compare the height of constituents in the actual compound and the other given mixtures.
The correct answer is: Only W and Y
Chromatography is a laboratory technique for the separation of a mixture into its components. The mixture is dissolved in a fluid solvent (gas or liquid) called the mobile phase, which carries it through a system (a column, a capillary tube, a plate, or a sheet) on which a material called the stationary phase is fixed.
To identify the components which are present in the protein we have to observe the protein extract column and then check which which component are coming with the same height in the chromatograph. Only W and Y are present.
