Sugars cross the brush border membranes of small intestine by various routes: two Na+-dependent carriers for both free D-glucose and D-galactose (which, in the presence of a gradient in electrochemical potential of Na+, are accumulated against their own concentration gradient); one Na+-independent non-concentrative carrier for D-fructose; various minor disaccharidase-associated systems for the transport of some of the monosaccharides arising from the disaccharides.
两种依赖钠离子的载体分别用于转运游离的D-葡萄糖和D-半乳糖（在钠离子电化学势梯度存在的情况下，它们会逆着自身浓度梯度进行积累）；一种不依赖钠离子的非浓缩性载体用于转运D-果糖；还有各种与二糖酶相关的次要系统，用于转运二糖分解产生的一些单糖。
