(6) The structure of the polypentapeptide is one of limited order below 20 degrees C which undergoes an inverse temperature transition to a conformation characterized by a regularly recurring beta-turn at 40 degrees C.

(10) A protein liquid membrane composed of coacervated alpha-elastin, a chemical fragmentation product of the biological elastic fiber protein, functioned as an amphoteric liquid ion-exchange membrane.
(11) The source, preparation, and properties of phase-separated systems such as lipid layers, coacervate droplets, sulphobes, and proteinoid microspheres are reviewed.
(12) The advantages of the coacervate systems over other models for protein binding studies of drugs are discussed.
(13) H-(Ala-Pro-Gly-Gly)n-Val-OMe did not coacervate even at as high a temperature as 100 degrees, and H-(Ala-Pro-Gly-Val-Gly)n-Val-OMe did not coacervate; however, it precipitated irreversibly around 65--70 degrees C. This suggests the critical role of the Val-Pro hydrophobic side chain interaction in coacervation.
(14) Electrophoresis and gelatin adsorption studies revealed that encapsulation by way of simple coacervation by gelatin is caused by the affinity between core and coacervate resulting from gelatin adsorption on the core surface.
(15) Recovery of the product as water-insoluble discrete units required the use of formaldehyde and isopropanol for coacervate denaturation and flocculation, respectively.
(16) Spherical droplets of clofibrate, prepared by a capillary jet method, were encapsulated in gelatin by simpel coacervation, using sodium sulfate as the coacervating agent.
(17) Terbutaline sulphate microcapsules were prepared by coacervation-phase separation induced by solvent evaporation technique.
(18) Yields and equilibrium water contents of complex coacervates from these polymers were measured, and microcapsule forming systems based on this effect were developed as potential prostheses for organ transplantation.
(19) The stability ranges of the coacervates under varying conditions of temperature, pH, salt concentration and concentration of added organic solvent have been investigated with results that suggest a marked sensitivity of elastin conformation to solution conditions.
(20) In complex coacervation method optimal ratio was 0.5:1.
