Übersetzung für "Enzymatic action" in Deutsch

The enzymatic action continued for 15 hours under continuous agitation.

According to their definition, they are proteins which bind strongly to carbohydrate but do not exercise any enzymatic action.

It was furthermore found that the special protein used in combination with the simple sugars produced by the enzymatic action does not spoil the fruit juice flavor of the drink or alter it in any way, so that the conditioning drink is very tasty.

The soybean trypsin inhibitor present in the test system has the function of selectively inhibiting the plasma kallikrein activated concurrently with the activation of factor XII to factor XIIa so as to prevent its enzymatic action on the tripeptide derivative used as substrate.

According to the invention, this object is achieved in that a solution of the thus purified plasminogen is adjusted to a plasmin activity ranging between 0.005 and 0.2 ?moles/ml min, preferably 0.01 and 0.1 ?moles/ml min, relative to the chromogenic substrate H-D-valyl-L-leucyl-L-lysine-p-nitroanilide dihydrochloride, is maintained at a temperature of from +1° C. to +20° C., preferably of from +4° C. to +12° C., for a period of from 6 to 60 hours, preferably 15 to 50 hours, in order to provoke an enzymatic-proteolytic conversion of plasminogen into lys-plasminogen, whereupon the enzymatic action is interrupted and lys-plasminogen is isolated.

The L-phenylalanine liberated from the methyl ester by the enzymatic action was quantitatively determined with the aid of an amino-acid analyzer and was used as a measure of the cleavage activity (1 enzyme unit (1 U) is the amount of enzyme which forms 1 ?mol of phenylalanine/min).

In addition, when the secondary amines, in particular the cyclic, bicyclic or oligocyclic secondary amines, are used in enzyme-containing detergents with bleaching systems, the enzymatic action is not or only negligibly adversely affected, or is even improved, by the bleaching system.

Thus within the scope of the method according to the present invention the inhibition of the enzymatic action of activated protein C is determined depending on LA antibodies.

The third substrate category concerns those amides from which, by enzymatic action, there are split off aminophenols, phenylenediamines or other aromatic amines which, in the range of visible light, do not absorb sufficiently and, therefore, require a subsequent reaction for a color formation.

In other processes, the amount of dyestuff or other molecular groups which are split off, by enzymatic action, from starch to which a dyestuff or other molecular groups are bonded is measured.

A method for assaying blood coagulation factor XII in human blood plasma wherein plasma is treated with an activator in order to convert factor XII present in the plasma into factor XIIa, the latter is reacted with a tripeptide derivative which is split by the enzymatic action of factor XIIa and forms a colored or fluorescent split product, and the quantity of this split product is measured photometrically, spectrophotometrically or fluorescence-spectrophotometrically.

Absorption and metabolism: As part of the fat metabolism process, linoleic acid is broken down by mechanical and enzymatic action in the gastrointestinal tract (mouth, stomach, and small intestine).

The cholesterol liberated in these lipoproteins reacts immediately as a result of the enzymatic action of the cholesterolesterase (CE) and cholesteroloxidase (CHOD), and hydrogen peroxide is produced.

The release of the active ingredients from the solid bodies conventionally takes place during the application of the compositions containing them, by destruction of the shell or the matrix, preferably as the result of mechanical, thermal, chemical or enzymatic action.

During the manufacture and storage of fibrinogen preparations, further fibrinogen split products may form to a varying degree by enzymatic action at the cost of functionally intact fibrinogen, leading to an impairment of the quality of a fibrinogen preparation, and in particular, to an impairment of the reconstitution of freeze-dried fibrinogen.

The active ingredients are typically released from the capsules during the use of the compositions that comprise them through destruction of the shell or the matrix as a result of mechanical, thermal, chemical or enzymatic action.

By using extremely slight amounts of plasmatic enzyme, the method according to the invention also does with slight amounts of inhibitors to interrupt the enzymatic action.

The enzymatic action within the solution is interrupted after the conversion with aprotinin, the solution is lyophilized and, if desired, the lyophilisate is heat-treated.

Chemical compounds of the invention which irreversibly inactive the enzymatic action of active intracellular catalase of live microorganisms such as bacteria and/or fungi, in particular molds and/or yeasts, bring about the death of these microorganisms.

The invention relates to sulfonyl esters of the general formula R 1 —COO—SO 2 —Z—R 2 in which Z, R 1 and R 2 have the meanings defined in claim 1, to a use of these compounds for modifying the kinetics of the enzymatic action of catalase, to a method for measuring a concentration of live and/or active microorganisms such as bacteria and/or fungi, especially molds and/or yeasts, in a liquid sample by means of the evolution of oxygen from hydrogen peroxide, and to an apparatus for carrying out this method.

However, measurement errors result from the enzymatic action of active endogenous catalase from a wide variety of sources present in the sample.

Foodstuffs contain non-microbial endogenous catalase which is introduced into the sample by plant constituents (lettuce, onions), juice (apple juice, lemon juice) and animal tissue (erythrocytes in meat and milk), and markedly falsifies the measurement through its enzymatic action unless the action of this non-microbial endogenous catalase has been previously eliminated for example by heat treatment (pasteurization, preservation).
