Pna chemistry
Webamino groups of PNA monomers is based on either Boc or Fmoc chemistry (23–25). The postsynthetic modification of PNA uses coupling of a desired group to an introduced lysine or cysteine residue in the PNA (23, 27). Amino acids can be coupled during solid-phase synthesis or compounds con-taining a carboxylic acid group can be attached to WebAmino acid analysis plays an important role in research in many fields such as chemistry, bioengineering, food science, and clinical medicine. Amino acid analysis can be divided into two categories according to whether it is derivatized, one is the direct analysis method, and the other is the derivatized indirect analysis method.
