normally it exists as zwitter ion.(as shown previously)
in pH<7,protonation will take place,so carboxylic acid ion will get H+ and it exists as acid,it will have NH3+ ion.
if pH>7,deprotonation will take place from NH3+ group,so it exists as amine,it will have COO- ion.
hope its clear
if not feel free to ask
!!!!!!!!!!!!!!!
