WebThe carboxyl group and the amino group that are to be excluded from peptide synthesis are protected (steps 1 and 1 ). Next the amino acid containing the unprotected carboxyl group is carboxyl-activated (step 2). This amino acid is mixed and reacted with the other amino acid (step 3). Protecting groups are then removed from the product (step 4).
