Question

casein is one of the most abundant proteins in milk. which one of these compounds should not cause its denaturation if we add them to a glass of milk? a) diluted saline solution b) 60% methanol c) citric acid ph=3 d) saturated saline solution

Explanation:

Proteins can be denatured by organic solvents like methanol, and by changes in pH such as adding citric acid. High - concentration salts like saturated saline can also cause protein denaturation. Diluted saline solution is a physiological - like solution and is less likely to cause protein denaturation.

Answer:

A. Diluted saline solution
