“…The synthetic ester evidently shows the primary melting point less well, but melts at a temperature well below that of the second melting point of the natural ester (158-162°as compared with 173-179°) {U26; cf. also 801,827,862).…”

II. METHODS or INVESTIGATION* Only the naturally occurring hile pigments of type IXa are discussed.* .\11 tlie al).s()r[)ti()ii curves of the "hiliverdiiis" in Heihiieyers hook (121-i) are ohviously tliose of niixtiirt's of liiliverditi witli hiliruliiii (pages 1(51, 1()7) and other * The term K-urobilin is, however, used by the Fischer school to denote a mixture of side chain isomerides of mesobilene-(b) in contradistinction to mesobilene-(b) IXa.* It is not certain, however, whether the albumin is the only plasma protein able to combine with hematin (c/. Miller and Ailing, 191f9a).* Keilin and Smith {1502a) have been unable to confirm the results of Virtanen and Laine.XII. HEMOGLOBIN CATABOLISM, II * Cf., however, Bittner and Watson {28-3a). CHAPTER XIII FORMATION OF HEMOGLOBIN AND SYNTHESIS OF PORPHYRINSIN THE ANIMAL BODY * The hemoglobin found occasionally in some species of Daphnia (Fox,937aa) does not appear to have an essential physiologic function, although, like the hematin compounds mentioned above, it is passed on in parthenogenetic eggs. Even the chlorocruorin or erythrocruorin of serpulimorphid worms does not appear to be essential (Fox, 937a).Glaucobilin. See Mesobiliverdin. Globan, 211. See also Globin (denatured).

“…In this connection the earlier observations of Schumm (18) and H. Fischer (16,19) must be mentioned. These' concerned the increase of urinary coproporphyrin after ingestion of blood or blood containing foods.…”

“…These' concerned the increase of urinary coproporphyrin after ingestion of blood or blood containing foods. It is en'tirely conceivable that coproporphyrin III might originate from protoporphyrin (16) derived from hemoglobin in the bowel, and it is equally conceivable that the coproporphyrin content of the urine might be increased in this way (16). The normal individual whose urine was used in the above investigation was not restricted as to diet, and ate considerable meat throughout the period of collection of the urine, so that small amounts of hemoglobin may have been supplied.…”
