The L -isomer of Asp is one of the 22 proteinogenic amino acids, i.e., the building blocks of proteins. Aspartic acid, like glutamic acid, is classified as an acidic amino acid, with a pKa of 3.9, however in a peptide this is highly dependent on the local environment, and could be as high as 14. Asp is pervasive in biosynthesis.
WebpI=1.88 +3.652=2.77. Calculate the isoelectric point of Lysine. Solution: Lysine has a basic group in its side chain. To calculate the isoelectric point of Lysine, the pKa of the similarly ionizable groups will be considered which are the ammonium group (pKa = 8.95) and the basic side chain (pKa = 10.53). pI=8.95+10.532=9.74.
