Page 379 - Laboratory of the Connecticut Agricultural Experiment Station and the Sheffield Laboratory of Physiological Chemistry in Yale University, New Haven.) (Received for publication, January 30, 1915.) When young albino rats are fed on a ration composed of isolated and purified protein, a carbohydrate like starch, inorganic salts furnished in the form of what we have termed

Page 68 - added, the tube is again heated to boiling to dissolve the precipitate, the contents of the tube are transferred quantitatively to a 10 cc. 51 volumetric flask, cooled, made up to the mark, shaken, and then filtered through cotton into the colorimeter chamber. The color is compared at once with that obtained from 0.64 mgm. of dextrose, 5 cc.

Page 68 - aliquots are measured out into large Jena test-tubes for duplicate determinations. Two cc. of saturated picric acid solution and exactly 1 cc. of 10 per cent sodium carbonate are added (as well as two glass beads and two or three drops of mineral oil), and the contents of the flask are evaporated rapidly over a direct flame until precipitation occurs. About 3 cc. of water
Page 502 - is the result of the decomposition of the proteins with sulphuric acid. The iodothyrin so obtained is about 4 per cent of the total weight of the dried thyroid. It has some physiologic activity, but the original claim of Baumann that it is the physiologically active principle of the thyroid has long since been disproved. Other decomposition products have been obtained by
Page 505 - solution is precipitated by copper hydroxide, and to a large extent by barium, calcium, and magnesium salts. It is almost entirely soluble in ethyl acetate, but by partial extraction with this solvent it is possible to separate A into two fractions. In the ethyl acetate soluble portion of A, the percentage of iodine
