The protein in aqueous solution absorbs ___________

The protein in aqueous solution absorbs ___________ Correct Answer UV light

The protein absorbs ultra violet light because of the presence of amino acid tyrosine and tryptophan. These amino acids are aromatic compounds which absorb UV light, both the amino acids have distinct absorption wavelength as well as distinct emission wavelength and has different quantum yield.

Phytase, an enzyme produced by Aspergillus niger can be adsorbed on microcrystalline cellulose powder (MCCP). The adsorption follows a Langmuir isotherm and the maximum concentration of the protein that can be obtained on the adsorbent is 70 mg cm-1. At a concentration of 50 mg L-1 of protein in the solution, the concentration of protein on the adsorbent reaches 35 mg cm-1. It is desired to recover 90% of the protein from 1.5 liter of the cell free culture filtrate containing 220 mg L-1 protein by addition of MCCP to the solution. The concentration of the protein adsorbed on the solid at equilibrium will be:

Directions : In each of the following questions a statement is given, followed by two conclusions. Give answer :

Statements : About 50 per cent of the animal by-products - hair, skin, horns etc. is edible protein. American chemists have developed a method of isolating 45 per cent of this protein. They used an enzyme developed in Japan to break down soya protein.

Conclusions :
I. Americans have not been able to develop enzymes.
II. Animal by-products protein has the same composition as soya protein.

A sample of polystyrene is warmed under reflux in concentrated nitric acid and the clear mixture is poured in water to yield a X coloured precipitate. This precipitate is then extracted with ether and then with NaOH solution followed by washing with water in each extraction.
