Answer:
At physiological pH,the carboxylic acid group of an amino acid will be deprotonated while the amino group will be protonated,yielding the zwitter ion form.
Explanation:
Deprotonated means removal of protons in an acid base reaction and protonated means addition of protons in an acid base reaction.
Both protonated and de protonated reaction takes place in catalytic acid bade reaction by changing either it's mass or it's charge.
During formation of zwitter ion, the carboxylic acid will be deprotonated by donating the H+ ion while the amino acid is protonated by taking the H+ ion.
