We also very much welcome your feedback and comments. Non-natural amino acids are incorporated into peptides for many different reasons. For example, unnatural amino acids are used to increase the activity or selectivity and plasma stability of peptides in drug discovery projects. Another example is the use of non-natural amino acids for the induction or stabilization of secondary structures helices, sheets, turns. JPT is proud to offer the custom peptide synthesis of peptides containing a plethora of different unnatural amino acids.
Besides commercially available amino acids, we are able to synthesize a wide range of non-commercially available amino acids. Please inquire about your specific peptide sequence to receive a quotation. JPT is also able to incorporate a wide range of unusual amino acids found in nature. Prominent examples are: hydroxyproline Hyp , beta-alanine, citrulline Cit , ornithine Orn , norleucine Nle , 3-nitrotyrosine, nitroarginine, pyroglutamic acid Pyr.

Unnatural amino acids: better than the real things?
Special protecting group for N-terminus. Amino acids carrying four different groups on their a-C atom i. These a-amino acids can be found in respective L- and D-forms enantiomers :. The predominant form in natural proteins is the L-form. As some enzyme classes are enantioselective, i. These heavy amino acids are non-radioactive, but 1 Da heavier than the standard amino acids. The standard heavy amino acids you can find:. Request A Quote. Polypeptid-display-bibliotheken und verfahren zur herstellung und verwendung davon.
