5-aminolevulinic acid, but not 5-aminolevulinic acid esters, is transported into adenocarcinoma cells by system BETA transporters.
TL;DR: 5-ALA, but not 5- ALA methyl ester, was found to inhibit cellular uptake of [3H]-GABA and [14C]-β-alanine, and is transported by β-amino acid and GABA carriers in this cell line.

Mechanistic interpretation of the influence of lipid phase transitions on transport functions.
L Thilo,H Träuble,Peter Overath +2 more
TL;DR: In an attempt to understand the mechanism by which a structural change of membrane lipids affects transport functions, the temperature dependence of transport rate has been measured to below the low temperature end of the fluid in equilibrium ordered phase transition of the membrane Lipids.

Microvillus membrane vesicles from pig small intestine Purity and lipid composition
TL;DR: The purity of the membrane vesicles were established by measuring the activity of marker enzymes and the RNA and DNA content, and the lipid composition was established and the membranes were found free of contamination by other subcellular membrane fragments, except for a minor contamination with basolateral plasma membranes.

Effect of the phase transition on the transbilayer movement of dimyristoyl phosphatidylcholine in unilamellar vesicles.
B. de Kruijff,E.J.J. Van Zoelen +1 more
TL;DR: The rate of transbilayer movement of dimyristoyl phosphatidylcholine shows a distinct maximum (half-time 4 h) in the temperature range at which the hydrocarbon phase transition occurs.

Lipid bilayer structure in the membrane of Mycoplasma laidlawii
TL;DR: X-ray diffraction patterns from intact, isolated Mycoplasma laidlawii membranes at temperatures above and below the thermal phase transition of the membrane lipids reveal important features of the molecular structure of the membranes.
Journal ArticleDOI
The effect of membrane lipid unsaturation on glycoside transport.
TL;DR: The data suggest that the membrane may exist in two physical states, one above and the other below a transition point determined by the composition of the lipid phase.

Temperature “breaks” in Arrhenius plots: A thermodynamic consequence of a phase change
TL;DR: Temperature “breaks” in Arrhenius plots of biological data are real and can be explained as a consequence of a phase change in the system.
