WebAn application of HSAB theory is the so-called Kornblum's rule (after Nathan Kornblum) which states that in reactions with ambident nucleophiles (nucleophiles that can attack from two or more places), the more electronegative atom reacts when the reaction mechanism is S N 1 and the less electronegative one in a S N 2 reaction. WebJan 20, 2024 · Glycosyl phosphosaccharides (GPSs) represent a large and important family of complex glycans, which are ubiquitously distributed in bacteria, yeasts, protozoan parasites and animals, and exhibit... WebThis enzyme catalyzes the reversible phosphorolysis of 6-oxypurine (deoxy)nucleosides to generate the corresponding purine base and (deoxy)ribose 1-phosphate. Hundreds of reactive trajectories were generated. Analysis of this transition path ensembles provides insight into the detailed mechanistic dynamics of reaction in the enzyme. florida avenue walk in clinic
