Density Functional Studies on Secondary Amides: Role of Steric Factors in Cis/Trans Isomerization

Molecules, 2018
Cis/trans isomerization of amide bonds is a key step in a wide range of biological and synthetic processes. Occurring through C-N amide bond rotation, it also coincides with the activation of amides in enzymatic hydrolysis.

Self-Assembly of the Dipeptide L-Alanyl-L-Phenylalanine under the Action of Methanol Vapor with the Formation of Micro- and Nanostructures

Учёные записки Казанского университета: Серия Естественные науки, 2023
The mechanism of self-assembly by short-chain peptides (oligopeptides) – the process by which their molecules spontaneously form an ordered structure – has received much attention recently.

Cyclic Dipeptides Formation From Linear Dipeptides Under Potentially Prebiotic Earth Conditions

Frontiers in Chemistry, 2021
Cyclic dipeptides (DKPs) are peptide precursors and chiral catalysts in the prebiotic process. This study reports proline-containing DKPs that were spontaneously obtained from linear dipeptides under an aqueous solution. Significantly, the yields of DKPs
