In December, 1913, Referee A made a large number of new tests to determine proteolytic and amylolytic power.
For the proteolytic test I used fresh, well washed fibrin and examined samples of Lactopeptine powder numbered as follows: No.
Report of Referee A In view of the manufacturer’s reiteration of the claims for Lactopeptine powder, I have carried out further experiments to determine its proteolytic and amylolytic power.
The digestion or dissolving of proteid matter byproteolytic ferments.
A proteolytic ferment, or enzyme, present in the pancreatic juice.
An unorganized proteolyticferment or enzyme contained in the secretory glands of the stomach.
Defn: A proteolytic ferment, like trypsin, present in the juice of the green fruit of the papaw (Carica Papaya) of tropical America.
Defn: An unorganized proteolyticferment or enzyme contained in the secretory glands of the stomach.
Defn: The digestion or dissolving of proteid matter by proteolytic ferments.
Defn: To convert into peptone; to digest or dissolve by means of a proteolytic ferment; as, peptonized food.
Defn: A proteolytic ferment, or enzyme, present in the pancreatic juice.
The metabolism of the carbohydrates already mentioned is accompanied by that of the nitrogenous constituents, the reserve protein of the sub-aleurone layer being attacked by proteolytic enzymes and broken down into simpler compounds.
Protein hydrolysis requires the presence of a certain amount of moisture, and if this be removed too rapidly by a forced draught at the early stages of kilning the proteolytic enzymes cannot perform their function.
If, on the other hand, the grain be loaded in too moist a condition, and the temperature be raised too quickly, the proteolyticenzymes lose their activity and the proteins remain for the most part unattacked.
It is now known that proteolytic enzymes exist in finished malt, and that, when the mashing process is conducted under certain conditions, these are able to degrade and render soluble some of the higher proteins present in the malt.
Many of the enzymes present in bacteria, especially the proteolytic ones, are not any more sensitive to heat than are the antigens, hence are not destroyed entirely.
The administration of cultures of this organism is indicated in all cases of intestinal ailments, caused by the excessive growth of proteolytic bacteria, and consequent putrefaction of foods in the alimentary tract.
The importance of the organism lies in the fact that, as in the case of Bacillus bulgaricus, it kills all pathogenic non-sporing germs and also destroys all proteolytic gas-forming bacilli in milk.
The darker liquefied portion of the tube-contents is due to digestion of the curd by proteolytic bacteria, thus indicating impure culture.
Here, again, there is evident peptonisation of the curd, thus indicating infection byproteolytic ferments.
With the proteolytic ferment of pineapple juice my observations have led me to the following conclusions, viz.
This, I think, furnishes an excellent illustration of the way in which catalytic agents, such as the proteolytic enzymes, may be supposed to act.
Further, we find partial substantiation of this view in the results obtained by Wurtz[33] in his study of the vegetable proteolytic ferment papain, and in my own results from the study of the proteolytic ferment of pineapple juice.
Its proteolytic action is therefore carried on, under normal circumstances, in an alkaline-reacting fluid containing 0.
Such a peptone exposed to the proteolytic action of trypsin should obviously break down in part into simple crystalline bodies, leaving a residue of true antipeptone.
The above facts furnish us, I think, a good illustration of how dependent these proteolytic enzymes are upon the proper conditions of temperature, to say nothing of other conditions, for the full exercise of their peculiar power.
To be sure, the rate of absorption is greatly increased when the albumin has been peptonized, but still absorption of the native proteid is possible without the agency of proteolytic enzymes.
It must be remembered, however, that in spite of oft-repeated attempts to obtain more definite knowledge regarding the composition of theseproteolytic enzymes our efforts have been more or less baffled.
The only further information as to the composition of this preparation is the statement that “the dialysate of this blue fatweed is said by the manufacturer to contain a proteolytic ferment.
As the product is said to contain papain, the presence of enzymes was tested for, with the result that it was found to possess neither proteolytic nor amylolytic properties.
The following, so far as it means anything, seems to confirm the correctness of the report of the Council’s referee that Ingluvin is practically devoid of proteolytic activity: “.
Pharmacopeia for estimating the strength of pepsin were found to possess little, if any, proteolytic activity.
There are, however, certain CO-NH linkages which are not attacked by proteolytic enzymes and some peptones soluble in absolute alcohol, so that these two characteristics do not bar it from the group of proteins.
The presence of proteolytic enzymes in most vegetative cells, and in seeds, may be demonstrated, however, by studying the action of extracts of these tissues upon soluble proteins.
In general, all proteolytic actions, even when accelerated by active enzymes, proceed much more slowly than do the hydrolyses of carbohydrates or fats.
This ferment, called by them galactase, on account of its origin in milk, is a proteolytic enzym of the tryptic type.
Contrary, however, to what is found in the case of the venoms of Vipera and Lachesis, the secretion of Ornithorhynchus is devoid of hæmolytic and proteolytic properties.
The bacteria that bring about this fermentation may be divided into several groups on the basis of their morphology, proteolytic activity, gas production, temperature adaptation and production of substances other than lactic acid.
Proteolytic changes in the ripening of Camembert cheese, U.
This author, however, associates their activity with proteolytic rather than with carbohydrate metabolism.
Reasoning from this experience, she suggests that the action of the accessory growth factors is to increase the reaction velocity of the proteolytic metabolism.
These results are in harmony with the bacteriological study of Torrey and Hess, who found that there was no increase in the proteolytic flora of the intestine in infants or in guinea-pigs suffering from scurvy.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "proteolytic" in a variety of sentences. We hope that you will now be able to make sentences using this word.
