WebWater soluble drugs are mainly released by diffusion of dissolved drug molecules across the gel layer, while poorly soluble drugs are mainly released by erosion mechanisms. Modulation of drug release rate has been achieved by incorporating pH-independent hydrocolloids gelling agents or adding polycationic hydrocolloids such as chitosan [ 61 , 62 ].
WebJun 19, 2024 · Hexanoic acid [CH 3 (CH 2) 4 COOH] is barely soluble in water (about 1.0 g/100 g of water). Palmitic acid [CH 3 (CH 2) 14 COOH], with its large nonpolar hydrocarbon component, is essentially insoluble in water. The carboxylic acids generally are soluble in such organic solvents as ethanol, toluene, and diethyl ether. WebAug 29, 2004 · The folded state is stabilized mainly by the burial and tight packing of over 80% of the peptide groups and non-polar side chains. If life as we know it is to exist in a solvent other than water, the folded state must be stable and soluble in the new solvent. Our analysis suggests that proteins will be unstable in most polar solvents such as ...
