Physiology and Hygiene for Secondary Schools Flesh contains no starch or sugar, but a small quantity of glycogen. The Chemistry of Food and Nutrition A simple investigation of freshly inflamed tissue is sufficient to show that the cells which have wandered from the blood stream soon contain glycogen. Histology of the Blood Normal and Pathological It converts a large share of the grape-sugar and partially digested starch brought to it into a kind of liver starch, termed glycogen, which it stores up in its tissues. Science in the Kitchen. In the presence of diastase, glucose yields glycogen and water, which, reacting together in the opposite direction, yield glucose again. Popular Science Monthly Oct, Nov, Dec, 1915 — Volume 86 The one exception is dextrose, which is a simple sugar; but even this is combined in the liver and the muscles to form the more complex compound known as glycogen. Physiology and Hygiene for Secondary Schools Cullingworth had strong views upon the subject, holding that the waxy matter was really the same thing as the glycogen which is normally secreted by the liver. The Stark Munro Letters Ehrlich shewed that the liver cells of a rabbit's liver, rich in glycogen, appear in dry preparations as bulky polygonous elements, of a uniform homogeneous brown colour, surrounded by a thin, well-defined yellow membrane. Histology of the Blood Normal and Pathological In fact, the small amount that is found in the tissue, and that compares to the glycogen found in animal tissues, is not present in sufficient quantities to merit consideration. Woman's Institute Library of Cookery Volume 3: Soup; Meat; Poultry and Game; Fish and Shell Fish The human body contains a small amount of a substance called glycogen, which is an animal starch or sugar. Maintaining Health Formerly Health and Efficiency It is a chief function of the liver to collect the excess of dextrose from the blood passing through it, and to convert it into glycogen, which it then stores within its cells. Physiology and Hygiene for Secondary Schools It secretes the bile, neutralizes many of the poisonous substances and end products of digestion that are taken up by the absorbing vessels of the intestine, and acts as a storehouse for the glycogen. Common Diseases of Farm Animals In cells that were not too rich in glycogen, small roundish bodies, clearly of a protoplasmic nature, of a pure yellow, can be seen embedded in the homogeneous cells that are coloured brown with glycogen. Histology of the Blood Normal and Pathological In addition, they contain a substance that most flesh foods lack in any quantity, namely, carbohydrate in the form of glycogen, and for this reason are said to resemble milk closely in composition. Woman's Institute Library of Cookery Volume 3: Soup; Meat; Poultry and Game; Fish and Shell Fish Some starch and sugar can be put aside as either glycogen—animal sugar—or be changed into fat. Maintaining Health Formerly Health and Efficiency As this is used, the glycogen in the liver is changed back to dextrose and, dissolving, again finds its way into the blood. Physiology and Hygiene for Secondary Schools Thus we have animal starch, or glycogen, stored up in the liver. A Practical Physiology The hyaline cellular ground substance, carrying the glycogen, could not under any circumstances be stained, but the cell-granules above mentioned stained easily with all kinds of dyes. Histology of the Blood Normal and Pathological Moreover, the process of liberation of sugar from glycogen itself in the liver, upon demand, is today set down to the action of an internal secretion, adrenalin. The Glands Regulating Personality Instead, I found an extraordinary amount of the substance and products of glycogen. The Dream Doctor In the consumption of stored material the glycogen is used first, then as a rule the fat, and last of all the proteids. Physiology and Hygiene for Secondary Schools It is called glycogen, or liver sugar, and is easily converted into grape sugar. A Practical Physiology On comparing these results with those of more recent investigation of the cells, it is easy to determine the location of the glycogen very accurately. Histology of the Blood Normal and Pathological Extraction of the liver then revealed the presence in it of a form of starch, an animal starch, which Bernard called glycogen, the sugar-maker. The Glands Regulating Personality If the activities are consummated, the fuel—glycogen—and the activating secretions from the thyroid, the adrenals, the hypophysis are consumed. Origin and Nature of Emotions In a sense the storage of fat by connective tissue cells and of glycogen by the liver cells is assimilation. Physiology and Hygiene for Secondary Schools The hepatic cells appear to manufacture this glycogen and to store it up from the food brought by the portal blood. A Practical Physiology It is also thought the glycogen thus deposited and stored up in the liver is little by little changed into sugar. A Practical Physiology If the activities were consummated, the fuel—glycogen— and the activating secretions from the thyroid, the adrenals, the hypophysis, would be consumed. Origin and Nature of Emotions We have stated that the emotions cause increased output of glycogen. Origin and Nature of Emotions As glycogen chiefly by the liver, but to some extent by muscle cells.
