Decarboxylation is the removal of a carboxyl group from an amino acid which leaves an amino group causing the pH to go higher

Explanation:

The amino acid, alanine for instance, undergoes decarboxylation (loss of its single carboxyl group) and yields ethyl amine.

The amino group left becomes the main functional group. Thus, it causes the compound to act basic, with a higher pH.
