Non-canonical Amino Acids (ncAAs) enhance the repertoire for building synthetic peptides. Their benefit is that they offer the option to modify the binding characteristics of a given synthetic peptide or protein, and they can affect the susceptibility towards proteolytic degradation. Thus, they may be used to control and enhance potency, stability, specificity, and other important parameters of APIs.
