Value for our tyrosine will be five five. And once again, as that PH value, the PH value of five five, all these charges will exactly cancel out. And so if we place our amino acid on this line here, it will not move in this direction, nor will it move in this direction. Now, by the way, what happens if I take this molecule and place it, let's say somewhere here, where at this location, when it is to the right of the pi value, this molecule will tend to want to move back in this direction. And that's because anywhere in this region, this molecule will have a net negative charge. And so, because this negative charge will cause it to move this way, it will gravitate towards our pi value.
