In chemistry, protonation is the addition of a proton (H+) to an atom, molecule, or ion. Protonation is possibly the most fundamental chemical reaction and is a step in many stoichiometric and catalytic processes. — “Protonation - Wikipedia, the free encyclopedia”, en.wikipedia.org
The pKa of a compound is determined by many things, but most significantly it is impacted by the stability of the conjugate base,  See also. Protonation. Hydronium.

The catalytically competent protonation state (CCPS) is the catalytically active protonation state of an enzyme. The protonation state Glu35H,Asp52- is thus the catatlytically competent protonation state of HEWL, where H denotes the protonated form of the Glu. — “Catalytically competent protonation state - Wikipedia, the”, en.wikipedia.org
