The invention concerns novel cationic and/or amphoteric oligomers obtained by: (a) condensing polyvalent hydroxycarboxylic acids with tertiary amines of formula (I), in which R<1> and R<2>, independently of each other, stand for alkyl groups having 1 to 4 carbon atoms, R<3> stands for an...
Ananion, pronounced [an-ahy-uhn ], is a type ofion—an electrically chargedatomor group of atoms. Acationis a type of ion for cats (OK, fine, that’s not true, but it is pronounced [kat-ahy-uhn ] ). But seriously:anionsandcationsare both ions. The difference is in the electrical...
We have studied activation by Na or Rb ions of different modes of the Na-K pump, using vesicles reconstituted with kidney Na-K-ATPase. The shape of the activation curves, sigmoid or quasi-hyperbolic, depends on the nature of the at the opposite surface and not on the specific mode of ....

Mg is a major cation universally essential for life (class (i)). Hundreds of enzymes require Mg to be catalytically active, including most reactions that use ATP or other nucleotides. Although total cellular Mg is often in the range of 100mM (Nierhaus, 2014), ∼90% of this is complexed...
A novel fullerenyl cation (EtO)2P+(OH)CH2−C60+ was generated by simply dissolving the monofunctionalized hydrofullerene RC60−H or singly bonded dimer RC60−C60R (R = CH2P(O)(OEt)2) in oxidizing acids such as H2SO4 and FSO3H. The cation was also formed in CH2Cl2 by one-electr...
