New amino acids are always added onto the carboxylic acid tail, never onto the amine of the first amino acid in the chain. Although the journal has a demanding peer review process, MCRE still boasts rapid publication, due in part, to the length of the submissions. Reagents While peptide synthesis often uses excess reagents, care is taken to develop synthesis methods that use reagents efficiently. Chemical synthesis of peptides is a very special branch of organic synthesis, and there are mainly two methods of liquid-phase synthesis and solid-phase synthesis at Chemical synthesis of peptides and proteins. These are added in sequence onto the growing peptide chain, which is attached to a Neuropeptides are synthesized from large, inactive precursor proteins called prepropeptides. The overall process goes like this:Remove the FMOC protecting group from the amine side of the amino acid.Add the next amino acid in the chain and coupling activation reagents.Repeat steps 1 and 2 until the sequence is complete.Cleave the peptide from the resin.
