(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.

(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.
Liquid
Definition:
(a.) Flowing freely like water; fluid; not solid.
(a.) Being in such a state that the component parts move freely among themselves, but do not tend to separate from each other as the particles of gases and vapors do; neither solid nor aeriform; as, liquid mercury, in distinction from mercury solidified or in a state of vapor.
(a.) Flowing or sounding smoothly or without abrupt transitions or harsh tones.
(a.) Pronounced without any jar or harshness; smooth; as, l and r are liquid letters.
(a.) Fluid and transparent; as, the liquid air.
(a.) Clear; definite in terms or amount.
(n.) A substance whose parts change their relative position on the slightest pressure, and therefore retain no definite form; any substance in the state of liquidity; a fluid that is not aeriform.
(n.) A letter which has a smooth, flowing sound, or which flows smoothly after a mute; as, l and r, in bla, bra. M and n also are called liquids.
