Question

Which among the following is/are egg white proteins ? A. Ovalbumin B. Livetin C. Lysozyme D. Ovomucin E. Phosvitin

• A. A, B, C Only
• B. A, D, E Only
• C. B, C, D Only
• D. A, C, D Only

Hint:

Always refer to established scientific literature for the names of proteins. Livetin is not a recognized term in this context.

Answer 1

The Correct Option is D

Step 1: Concept
Egg white proteins are a group of proteins found primarily in the egg white (albumen). These proteins play various roles such as providing nutrition and structural support for the developing embryo. Understanding these proteins is important in food science, biochemistry, and nutrition.

Step 2: Meaning
Ovalbumin, lysozyme, ovomucin, and phosvitin are specific egg white proteins with distinct functions. Livetin is not a recognized protein name in this context.

Step 3: Analysis
- Ovalbumin (A): The most abundant protein in egg whites, responsible for providing nitrogen to the developing embryo. - Lysozyme (C): An enzyme that helps protect against bacterial infections by breaking down cell walls of certain bacteria. - Ovomucin (D): A glycoprotein that contributes to the thickening and coagulation properties of egg whites when heated. - Phosvitin (E): A protein phosphate involved in calcium binding, which is crucial for the stability and function of other proteins. Livetin does not correspond to any known egg white protein.

Step 4: Conclusion
The correct answer includes Ovalbumin, Lysozyme, and Ovomucin. Final Answer: (D)
