The other approach is to introduce backbone protecting groups which will prevent the formation of hydrogen bonds. Such protection is made by the introduction of the Hmb group on the αnitrogen [53]. It has been shown that the presence of a Hmb unit every 6-7 residues is sufficient to disrupt the peptide aggregation [54]. The Hmb protected amino acid is introduced under the form of N,O-bis-Fmoc-N-(2hydroxy-4-methoxybenzyl) derivative, the O-Fmoc protection being cleaved during the following piperidine treatment. At the end of the synthesis the Hmb group is cleaved in the final TFA cleavage.

Now that we’ve described DNA and RNA, it’s time to take a look at the process of protein synthesis

Learning outcomes Describe the structure of an amino acid. Describe the formation and breakage of peptide bonds in the synthesis and hydrolysis of dipeptides.

Proteasomes are protein complexes which degrade unneeded or damaged proteins by proteolysis, a chemical reaction that breaks peptide bonds

As mentioned above, the generation and disappearance of Fmoc based chromophors allows the monitoring of the synthesis. Furthermore, samples may be taken to determine the load of Fmoc peptide. The completion of the deprotection reaction may be checked by cleaving samples and analyzing the obtained peptide.
