Tyrosine (Tyr or Y) or 4-hydroxyphenylalanine is one of the 22 amino acids that are used by cells to synthesize proteins. It is a non-essential amino acid with a polar side group. Its codons are UAC and UAU.
Tyrosine is a triprotic, dibasic amino acid with pKa of 2.17, 9.19, and 10.47 The first proton is removed from the carboxylic acid, the second from the ammonium group. The third proton, with a pKa of 10.47, is the phenolic proton from the amino acid side chain.This case is of interest because the acid is dibasic.or the triprotic acid, the a are. Second, the titration curves are calculated using a working equation for a triprotic acid being titrated with a strong base. The appropriate equation is. This equation is derived on a different page.
