And now the hydrogen, which bears a partial positive charge, can interact with the negatively charged oxygen atom of the side chain of the aspartate 94 amino acid. And this forms a salt bridge. A salt bridge is basically a stabilizing electric interaction between these two adjacent atoms. And by forming this sold bridge, we essentially decrease the net charge in that localized region and that stabilizes the T state, the 10th state of that deoxy hemoglobin molecule. And what that does is it lowers definitive hemoglobin for oxygen and makes it more likely to unload that oxygen to the tissues of our body. And that means it shifts the entire curve to the right side.
