Abstract:Membrane transport of small, non-polar gas molecules, such as O 2 and CO 2 , is among fundamental processes of living cells. Because of their size and chemical properties, these molecules may unimpededly transit through the lipid phase of the membrane. However, varying degrees of gas permeability in membranes with different lipid compositions have been reported experimentally, suggesting involvement of protein channels, particularly aquaporins (AQPs), in gas transport across membranes. To account for membrane … Show more
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.
