No less important than the correct proportions of the ingredients, is freedom from disease germs and bacteria of putrefaction. Complete sterilization is possible by prolonged boiling; but experience has proved that under prolonged exposure to a temperature near the boiling-point certain changes take place in the albuminoids of the milk which greatly impair its digestibility.
The elimination of albuminoids, as shown by the altered condition of the blood after menstruation, is greater than can be accounted for by the blood discharged. When the menopause is attained suddenly, the retention of such albuminoid substances must act toxically.
He found that albuminoids derived from decaying vegetable substances did not have the same effect. His discoveries led him to believe that the alkaloids of putrefaction produced in a cut or wound by the decaying of dead blood and tissue cells are the cause of the rapid multiplication of the neighboring live cells, which gradually fill the wound with new tissues.
Here it finds starch, oils, sugar, and substances called albuminoids, the sticky matter which you notice in wheat-grains when you chew them is one of the albuminoids. This food is all ready for the plantlet to use, and it sucks it in, and works itself into a young plant with tiny roots at one end, and a growing shoot, with leaves, at the other. But how does it grow? What makes it become larger?
She reared upon the dune a dark green parasol with a white border, and patted sand around the curved handle until it was, as she thought, firmly placed. Then she settled her skirts comfortably and opened her book, for the first time. "It looks bad," she mused. "Wonder what a carbohydrate is. And proteids where do you buy 'em? Albuminoids I've been from Maine to Florida and have never seen any.
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. But not so with the other substances.
They are rather complex chemical compounds, though not so complex as proteids. Since neither fats nor carbohydrates contain nitrogen, they are frequently classed together as non-nitrogenous foods. *Purpose Served by Carbohydrates, Fats, and Albuminoids.*—These classes of nutrients all serve the common purpose of supplying energy.
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.
Ten eggs are supposed to weigh a pound, and, unless they are unusually large or small, this is quite correct. Eggs contain from 72 to 84 per cent. of water, about 12 to 14 per cent. of albuminoids. The yolk is quite rich in fat; the white deficient. They also contain mineral matter and extractives.
It is a very common practice to feed horses accustomed to hard work the same ration when idle for a few days as when working. The blood of horses cared for in this way may become abnormally rich in albuminoids. The suddenness of the attack, occurring shortly after the animal is given exercise, indicates auto-poisoning.
