Peptidase - transition colloidal sludge or gel in a colloidal solution under the action of fluid or added substances, well adsorbiruyuschee sediment or gel, called in this case, peptization (for example, peptidase fat under the action of bile).
Cm. also Gels, Colloids.

Peptidase - separation units particles gels (jellies) or unconsolidated sediments under the influence of certain substances - peptization after coagulation of colloidal solutions. The result peptization sediment (or gel) goes into suspension. Baptistery adsorbed on particles gel (or coagulate), increase the hydration and the charge of its particles, which leads to the weakening of the link between them. When storing gels or precipitation their ability to P. decreases. Often called P. ions or molecules added outside of substances that are adsorbed on the surface of particles, increase their hydration. Sometimes P. occurs under the action of the substances resulting from the partial dissolution of the gel. More often, however, peptidase caused by the removal of ions that caused the coagulation; these ions can be removed from the surface of the particles addition of substances forming ions insoluble compounds. P. depends on the ratio of the number of baptistere and sediment. If baptistere not enough to Petrograd, then it is expressed in the loosening of the gel structure. P. plays an important role in living organisms, among phenomena of inanimate nature (P. clay and other minerals) and in engineering.
