Question

Which protein of egg binds biotin molecule?

• A. Conalbumin
• B. Avidin
• C. Flavoprotein
• D. Ovomucoid

Hint:

Remember, ”Avidin loves biotin.” This helps recall the strong binding property of avidin to biotin.

Answer 1

The Correct Option is B

Avidin is a glycoprotein found in egg whites. It tightly binds to the biotin molecule, forming one of the strongest known non-covalent bonds. This property is used in biochemical assays to capture biotinylated molecules.
