Question

Given the following pKa's, the isoelectric point of serine is ________. PK1 = 2.21 pK2 = 9.15 pK_R = 13

Quizplus · Accepted Answer

The isoelectric point (pI) of an amino acid with a neutral side chain, like serine, is calculated as the average of its pKa values for the carboxyl group (pK1) and the amino group (pK2). Thus, pI = (2.21 + 9.15) / 2 = 5.68.

Given the Following PKa's, the Isoelectric Point of Serine Is
