The lipase of castor oil seeds, a glycerol extract of the intestinal mucous membrane of the rabbit and pig, and an aqueous extract of bran have a slow hydrolytic action, whereas pepsin and trypsin are without effect.
The influence of small amounts of asparagine in enormously increasing the hydrolytic effect of amylase is an example.
These gums are generally considered to be decomposition products of celluloses, resulting from the action of some hydrolytic ferment, usually stimulated by some unfavorable condition of growth, some injury, or some morbid condition.
In other words, it is never possible to break off a disaccharide sugar from the molecule, either by the action of prunase alone, or by means of any other hydrolytic agent.
Schutzenberger in 1876 showed that when castor seeds are steeped in water, fatty acids and glycerol are liberated, and attributed this to the hydrolytic action of an enzyme present in the seeds.
B, 454) has shown that the hydrolytic activity of castor seeds is due entirely to the cytoplasm, which it is possible to separate by mechanical means from the aleurone grains and all other cellular matter.
The free acidity increases very rapidly, and is, doubtless, due to the decomposition of the neutral oil by the action of hydrolytic ferment.
In the lower qualities we have examples of the result of hydrolytic decomposition by enzymes, the free acidity often amounting to 70 per cent.
A motile bacillus, producing a green fluorescent colouring matter, but not identified, had a marked hydrolytic action and decomposed oleic acid.
Neither emulsin, arbutin nor crotin have any marked hydrolytic action on castor oil, but myrosin is about half as active as castor seeds, except in the presence of potassium myronate, when no decomposition occurs.
Nearly all of the digestive ferments are hydrolytic in their action.
Defn: One of a class of soluble products formed in the digestion of proteids with gastric and pancreatic juice, and also by the hydrolytic action of boiling dilute acids on proteids.
In general, the results of the action of the chemicals were in accord with the theory of hydrolytic association.
Incidentally new evidence bearing upon the theory of the hydrolytic dissociation of the molecule was adduced, together with facts that may throw some light upon the structure of the cell wall.
Lime plays its own hydrolytic part and assists the depilation by purely chemical action.
On entering the limes, the purely chemical hydrolytic action of lime is added to that of the bacterial enzymes as well as the action of lime as bacterial assistant, and the three continue to operate side by side.
The constituent groups have been investigated chiefly by hydrolytic methods.
The chemical action of added sulphide, and the simple hydrolytic action of calcium hydrate have their maximum activity in the new limes.
Any salt which is derived from a weak base or a weak acid (or both) is subject to hydrolytic action.
The siliceous residue is washed first with dilute acid to prevent hydrolytic changes, which would result in the formation of appreciable quantities of insoluble basic iron or aluminium salts on the filter when washing with hot water.
Such hydrolytic processes as the above are of great importance in analytical chemistry, especially in the understanding of the action of indicators in volumetric analysis.
This hydrolytic change is illustrated by the equation: (M.
As an extreme hydrolytic treatment the products were dissolved in 70 p.
Various intermediate terms of thehydrolytic series have been isolated.
This tissue is, therefore, a lignocellulose having the chemical characteristics typical of the group, but of less resistance to hydrolytic actions.
It is to be noted that the presence of the benzoyl group renders the cellulose more resistant to hydrolytic actions.
The hydrolytic transformation of starch to dextrins and maltose has been followed in this way, and the methods may serve as a model to which cellulose transformations should be approximated.
Next, it is known to us and is defined by the negative characteristics of resistance to hydrolyticactions and oxidations.
Next follows a group of processes which aim at producing a 'pure cellulose' by eliminating lignone constituents, for which the merely hydrolytic treatments of the Weende method are ineffectual.
It was, therefore, not improbable that profound hydrolytic changes should occur in the cellulose molecule when kept for prolonged periods as alkali-cellulose.
Furthermore, pepsin is limited in its action to the production of proteoses and peptones, while trypsin gives rise to a series of hydrolytic cleavages which result in the ultimate formation of comparatively simple bodies.
In other words, it is peculiarly adapted to take up the work where it has been left by pepsin and, if necessary, carry forward the hydrolytic change even to the extent of a conversion of the entire hemi-moiety into crystalline products.
In this hydrolytic cleavage of proteids the anti-group does not always appear as antialbumid.
In all of these cases it is obvious, from the method of treatment pursued, that the two bodies result from a simple hydrolytic cleavage of the proteid molecule.
An interesting suggestion was made by van't Hoff, who in 1898 expressed the idea that the hydrolytic enzymes should also act in the opposite direction, namely synthetically.
Very little is known concerning the reversible action of the hydrolytic protein enzymes.
It shows us how the cell can grow in the presence of hydrolytic enzymes and why in hunger the disintegration of the cell material is so slow.
While the hydrolytic action of enzymes is thus clear the synthesis in the cell is still a riddle.
This then would lead to the result that certain hydrolytic enzymes may have a synthetic action but not in the manner suggested by van't Hoff.
He considered this a case of a real synthesis of proteins from the products of itshydrolytic cleavage.
The effect of sodium chloride on the bacteriological results, like that on the hydrolytic constant, is anomalous.
The above figures are only applicable to the particular sample used; other samples containing different excesses of base would yield different hydrolytic values.
In solutions of bleach the hydrolytic action is retarded by the OH' due to the free base, and accelerated by the excess of H^{.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "hydrolytic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
