A “peptide bond” is an amide linkage (see Amides: Properties. Synthesis, and Nomenclature) that connects two amino acids, as in the “dipeptides” L-phenylalanyl-L-valine (below left) and L-leucyl-L-alanine (below right): See more Proteinogenicamino acids are the building blocks of proteins. In addition to the 20 amino acids directly encoded by the genome, two other amino acids are coded into proteins under special circumstances: selenocysteine … See more Let’s build a simple dipeptide between two of these amino acids. For simplicity’s sake, we’ll pick two from the “hydrophobic sidechain” group, … See more The good news is that we don’t have to stop at the dipeptide. If we choose protecting groups that can be removed selectively (and the … See more Yes. Rather than using the native amino acids and just praying for a good yield, we can useprotectedversions of L-Alanine and L-Leucine. If we … See more Webalum (fitkari), 3.
