WebSep 27, 2024 · What is Peptide Synthesis? Characterized by the formation of a peptide bond between two amino acids, peptide synthesis is, essentially, the production of peptides. Though peptide synthesis … WebThe peptide bond is planar and has two states: trans, ω ≈ 180°, and cis, ω ≈ 0°. In the trans configuration, the two alpha carbon atoms of the connected amino acids are on the opposite sides of the peptide bond, whereas in cis configuration they are on the same side of the peptide bond. In most cases, the peptide bonds in proteins are trans.
