Update on chiral recognition mechanisms in separation science
Journal of Separation Science, Volume 47, Issue 9-10, May 2024.The stereospecific analysis of chiral molecules is an important issue in many scientific fields. In separation sciences, this is achieved via the formation of transient diastereomeric complexes between a chiral selector and the selectand enantiomers driven by molecular interactions including electrostatic, ion‐dipole, dipole‐dipole, van der Waals or π ...

Biochemistry Research International, Volume 2024, Issue 1, 2024.Eg5 is a protein encoded by KIF11 gene and is primarily involved in correct mitotic cell division. It is also involved in nonmitotic processes such as polypeptide synthesis, protein transport, and angiogenesis. The scientific literature sheds light on the ubiquitous functions of KIF11 and its involvement in the onset and progression of different ...
