Since Most Proteins Contain Tyrosine, The Spectroscopic Measurement Of Light Absorption At 280nm Is A Convenient And Rapid Method For Estimating The Protein Concentration Of A Solution.


Q3: The Ovomucoid Present In Egg White Is A?

A. Metalloprotein
B. Glycoprotein
C. Lipoprotein
D. Nucleoprotein

Answer – Glycoprotein

  • Explanation: Glycoproteins Are Proteins Whose Prosthetic Groups Are Heterosaccharides Containing Hexosamine, Galactose, Mannose, Fucose And Sialic Acid. Glycoproteins Are Found In Mucous Secretions Of Mammals And They Function As Lubricating Agents. Egg-White Contains Ovomucoid Which Cannot Be Coagulated By Heat And Is A Glycoprotein.
