Negative beats positive: A channel composed of oligoether chains attached by amine groups to β‐cyclodextrin mediates the transport of halides across a phospholipid bilayer (see scheme) at faster rates than those observed for monovalent cations. Protonation of the amine linkages likely explains the preferential anion transport.

Eine Protonierung der Aminverknüpfungen erklärt vermutlich den bevorzugten Anionentransport.
scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
