This is a neutral Amini acid as it contain one free -NH2 and one
free - COOH group, to calculate the exact PI
value we should know the value of pka of free -NH2of thr and free -
COOH of ala. As these are not given so we can take a
generalization. Since it is a neutral amino acid it's PI will lie
between 5.5 to 6.3 .PI is the pH at which the net charge of a amino
acid is zero.
