[A multichannel transporter for glucose and amino acid transport].

Abstract

The recording of the short-circuit current responses to glucose or glycine was used to monitor active nutrient transport in the rat small intestine from mucose to serose. The coupled cotransporter for Na+ glucose and glycine was shown to consist of the central ion channel and a few nutrient channels around it. It seems that the combination of some types of ion channels with various types of nutrient channels leads to a formation of multi-channel transporters with different ion-nutrient specifics.
