There are at least five different sodium-dependent transport systems for amino acid uptake. The sodium-dependent transport is facilitated by energy derived from Na+/K+-exchanging ATPase at the basolateral membrane. Most energy-dependent transporters are coupled either to cotransport of Na+ or Cl- or to the countertransport of K+. An additional system of sodium-independent facilitated diffusion also exists and is predominantly geared toward basic and dipolar a amino acids. These passive transporters are either facilitated transporters or channels.
