Ions, acidicty, protein denaturation and my confusion.

(1/2) > >>

Carmel:
Hello everyone,

I understand how acidicity causes dentauration of proteins.

My question: why the hydrogen ions are the ones deciding about acidicity?

Why, for example, high concentration of sodium (which also brings a lot of electric charge) don't cause the same - denaturation by interaction with electric charges of protein aminoacids?

I wish a good day to everyone, whoever reads this  :)

This is a definition of acids.

There are many factors that cause protein denaturation

Carmel:
Thank you for your answer.

Unfortunatly it doesn't help a lot and the link doesn't work.

Once again:

Why high contentration of sodium ions doesn't make proteins loose secondary or tertiary structure?

What makes them diffrent from hydrogen ions in this matter?

AWK:
From wikipedia: Denaturation - "a concentrated inorganic salt"

Carmel:
Thank you.
