Hence the question of the chemical nature of the plasma-substances compels us now to look for a moment at the larger group of albuminoids to which they belong.
Albuminoids play the most vital rôle in plant life and are an extensive class of organic bodies found in plants and animals, as they are found to form the chief constituents of blood, nerves.
All albuminoids found in animals are produced by the processes fulfilled in plants.
Their function is the forming of albuminoids and other substances for higher purposes.

The albuminoids and gelatinoids, classed together as proteids, are the most important constituents of food, because they alone can supply the nitrogenous material necessary for the formation of the body tissues.
Both groups of compounds, however, supply the body with energy, and the gelatinoids in being thus utilized protect the albuminoids from consumption for this purpose.
For this purpose, the albuminoidsare most valuable.
The natural albuminoids (musculine) which constitute the real nutritive element of beef are congealed and surrounded by the fibrous tissue—that part which snarls up and renders the beef gristly and tough.
The albuminoids are also termed nitrogenous substances, and constitute the muscle making material.
They build and repair the nitrogenous materials, as those of muscle, tendon and bone, and supply the albuminoids of blood, milk and other fluids.
Gelatin when combined with the albuminoids and extractives has considerable nutritive value.
Technically, this is known as changing the albuminoids into peptones.
On account of this characteristic it is closely allied to those albuminoids known as fibrin, which is found in large proportions in animal blood.
These three varieties of albuminoids are contained in much greater proportion than in wheat flour, but the total albuminous matter in both wheat and rye flour are contained in about equal proportions.
The albuminoids are precipitated by boiling, the solution then filtered, evaporated in a vacuum at 60° C.
It will suffice us to know that, taken altogether, the active albuminoids of these venoms are numerous, and that each venom has its own particular active constituents, differing according to the species and variety of the snake.
The materials must first be exhausted with water slightly acidulated; then, after precipitating the albuminoids by boiling and defecating by adding lead acetate, the liquid is evaporated to one-half its volume and dialyzed in a vacuum.
The study of the last only, the albuminoids and diastases, interests us here.
Phallin is the type of those toxic albuminoids of unknown composition which exist in mushrooms, and which are comprised under the name sapotoxins.
Some food chemists wish to call the osseids, albuminoids; what were formerly termed albuminoids to be always spoken of as proteids only.
This is inferior in quality, and has a disagreeable smell imparted by the albuminoids which come in contact with the hot pan.
The second method is to place the fresh butter, or the residue from the former process, into tin pans and boil until the water is evaporated, when the albuminoids solidify at the bottom of the pans.
It has been shown that although it is possible that some of the fat of a fattening animal may be produced from the albuminoids of the food, certainly the greater part of it, if not the whole, is derived from the carbohydrates.
The quantity passed in twenty-four hours varies greatly, increasing not only with the water drunk, but with the albuminoids taken in with the feed and the urea produced.
In order to properly regulate the regimen of the obese, it is first necessary to determine the source of the superfluous adipose of the organism, since either the albuminoidsor the hydrocarbons may furnish fat.
In acute glaucoma the increase of albuminoids (blood proteids) is greater than in chronic glaucoma.
The aqueous humor, as has been pointed out by Uribe-Troncoso (Pathoginie du Glaucome 1903) contains a greatly increased quantity of albuminoids and inorganic salts in glaucoma.
The increase in albuminoids is a consequence of congestion and venous stasis and does not precede the attack.
Albuminoids is the anatomical name given to albuminous substances forming the connective tissues.
By the salivary diastase starch is converted into sugar and albuminoids are prepared for the action of the gastric juice.
Trypsin is the active ferment in this case (Kuhne), and it is only in alkaline or neutral solutions that the albuminoids are readily dissolved.
In such we may suppose the fault lies in the stomach digestion, where the albuminoids are converted into peptones, the intestinal digestion being active and normal.
He found that certain xanthines and albuminoidsderived from decaying animal matter were the most effective for this purpose and induced more rapid cell proliferation than any other substances he was able to procure.
He found that albuminoids derived from decaying vegetable substances did not have the same effect.
Though for normal children a restricted meat diet is desirable, in the case of defectives a rich supply of meat as well as of albuminoids in general is to be sought.
In short, the chief function of the albuminoids is to repair the machine, while the function of the other class of substances is to supply power.
It is natural that the albuminoids should have no specially allotted destination, since every part of the machine has to be maintained.
The albuminoids are properly plastic, destined to repair the tissues--although, owing to the carbon they contain, they are capable of providing energy on occasion.
The albuminoids are used to build up the organism, while the fatty and saccharine are burned in the body to keep it warm.
On the other hand, the assistance of the albuminoids is equally necessary to enable the fatty and saccharine foods to maintain the internal heat of the body.
Thus thealbuminoids cannot undergo the wonderful vitalizing process necessary to fit them to enter into and form part of the living body, except an adequate quantity of fatty matter be present to assist in the vital transformation.
The above list will hopefully give you a few useful examples demonstrating the appropriate usage of "albuminoids" in a variety of sentences. We hope that you will now be able to make sentences using this word.
