ChemElectroChem, Volume 12, Issue 12, June 10, 2025.This concept outlines the mechanism of molecular‐level multi‐electron storage, leveraging the quantum properties of electrons in σ bonds. Effective through‐space interactions between the 2pz atomic orbitals of electrophilic centers in organic superelectrophores enable the formation of supra‐LUMOs with bonding character, capable of hosting electrons ...

The Jackprot Simulation Couples Mutation Rate with Natural Selection to Illustrate How Protein Evolution Is Not Random [PDF]
, 2011 Protein evolution is not a random process. Views which attribute randomness to molecular change, deleterious nature to single-gene mutations, insufficient geological time, or population size for molecular improvements to occur, or invoke “design ...

Structure and Mechanism of the Divalent Anion/Na+ Symporter [PDF]
International Journal of Molecular Sciences, 2019 Integral membrane proteins of the divalent anion/Na+ symporter (DASS) family are conserved from bacteria to humans. DASS proteins typically mediate the coupled uptake of Na+ ions and dicarboxylate, tricarboxylate, or sulfate. Since the substrates for DASS include key intermediates and regulators of energy metabolism, alterations of DASS function ...

Na+-dependent and Na+-independent betaine transport across the apical membrane of rat renal epithelium [PDF]
, 2015 The low renal excretion of betaine indicates that the kidney efficiently reabsorbs the betaine filtered by the glomeruli but the mechanisms involved in such a process have been scarcely investigated.
