The mechanism of co-assembly different aromatic dipeptides has been studied using a combination microscopy and spectroscopy techniques. At an equimolar ratio, the kinetics process is favored giving rise to alternate copolymers.

in the present work, an extensive theoretical calculation study on histidine-histidine dipeptide in gas phase is done by using dft method with gaussian 98 program. through investigations on the molecular geometries of this molecule it is found that there is six rings in the molecules not two rings. the presence of four intramolecular hydrogen bonds is responsible for the formation of additional...

In order to accurately understand and estimate molecular properties, finding energetically favorable conformations is the most fundamental task for atomistic computational research on molecules materials. Geometry optimization based quantum chemical calculations has enabled conformation prediction of arbitrary molecules, including de novo ones. However, it computationally expensive perform geom...

Although it is reasonable to expect that the frequency of a generic dipeptide XY in proteins is the same of its counterpart YX, on the basis of an accurate statistical analysis of a large number of protein sequences, it appears that some dipeptides XY are considerably more frequent than their mirror images YX, referred to as antidipeptides. Given that it has been verified that this unexpected a...

Skin photoaging is characterized by wrinkles, laxity, and dryness cumulatively caused sunlight exposure. One of the major contributors to skin reactive oxygen species (ROS), which trigger inflammatory response collagen degradation. Cyclic dipeptides (2,5-diketopiperazines) present in various foods microorganisms are reported have antioxidant activity. We previously developed a unique hydrolysat...

A Hf-based NU-1000 metal organic framework as a hydrolytic nanozyme for peptide bonds in dipeptides and hen egg white lysozyme protein showed greater stability better recyclability than previous Zr-/Hf-based nanozymes.

Aims & Objectives: The present study consists in evaluation of the effects of the dipeptides Kyotorphin (Kyo) and D-Kyotorphin (D-Kyo) on nociception and plasma levels of adrenocorticotrophic hormone and corticosterone after 1 hour of heat stress in rats. Materials & Methods: Kyo and D-Kyo`s effects on nociception were evaluated by Paw pressure and Hot plate test after 1 hour of heat stress. Pl...
