Classification of Membrane Transporters
2005In summation, classification of membrane transporters is a challenging issue. One must consider not only their primary structure, but one must also ponder their function, topology, evolutionary origins, substrate specificity, and structural architecture.

Synthetic membrane transporters
Current Opinion in Chemical Biology, 2002An increasing number of synthetic compounds have been shown to facilitate ion and polar molecule transport across bilayer membranes. Most notably, recent advances in anion transport have yielded synthetic chloride channels and phospholipid translocases.

The proposed model allows estimating polymer membrane transport properties. It is based on a microscopic description of charge and water transport in a single capillary with a uniform distribution of charge at the wall. The equations are solved analytically for two geometries: cylindrical capillary and parallel plates.

The relative constancy of the internal environment of the cell is maintained by a variety of transport systems which are located within the membrane. These transport systems serve to regulate the entrance and exit of various solutes concerned with the metabolic activity of the cell.

Transport Phenomena in Membranes
Angewandte Chemie International Edition in English, 1969AbstractThe realization that many elementary biological processes occur at membrane‐like structures has led to renewed interest in the theory of molecular transport through membranes. Coupling phenomena in membranes, some of which are very complex, can now be rationally described with the aid of the thermodynamics of irreversible processes.

Many substrates cross cell membranes by processes other than passive diffusion. When the transport is carrier-mediated, e.g., facilitated diffusion, active transport, and exchange diffusion, the carrier modifies the conductance of the membrane and may either increase or decrease the flux of the substrate across the membrane.

Membrane transport and disease
Molecular and Cellular Biochemistry, 1989Four situations in which membrane transport is altered by disease are discussed: (a) non-specific leaks induced by poreforming agents; (b) glucose transport and cellular stress; (c) Ca2+-ATPase and hypertension; (d) Na+ channels and HSV infection.

Transport of Drugs across Membranes
Protoplasma, 1967In contrast to many compounds of physiological significance the penetration of drugs through membranes is, in general, passive, by diffusion or filtration. Most drugs are weak organic acids or bases, which in the unionized state are lipid soluble, but are hydrophilic when dissociated.
