Schistosome dipeptide of love

Trends in Parasitology, 2022
The female schistosome's dependence on the male to reach sexual maturity has puzzled scientists for decades. Using various molecular techniques, Chen et al. dissect the synthesis pathway of the β-alanyl-tryptamine dipeptide (BATT), emitted by the male into its environment, which induces sexual maturation and egg-laying in the female.

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.
