Abstract:The influence of oxalate on mucosal sulphate, selenate and selenite uptake in the sheep midjejunum was investigated. Oxalate significantly inhibited sulphate and selenate uptake, whereas mucosal uptake of selenite and L-leucine was not affected. Thus, the effect of oxalate on sulphate and selenate uptake appears to be specific. Besides oxalate, the dicarboxylate anions oxaloacetate and fumarate also significantly reduced mucosal sulphate uptake.The results suggest that oxalate and dicarboxylate anions with a s… 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.
