WebThe phenolic hydroxyl of tyrosine is significantly more acidic than are the aliphatic hydroxyls of either serine or threonine, having a pK a of about 9.8 in polypeptides. As with all … WebAlanine has a non-protic side chain (a methyl) , and thus at pH = 7.4 (physiological pH), the carboxyl group has a negative charge (COO-), and the amino group has a positive charge (RNH3+). Therefore, at pH 7.4, L-Ala is zwitterionic. Amphoteric molcules are not necessarily zwitterionic. Take for example ammonia (NH3). Ammonia has a pKa of 38.
