“…Photochemical Absorption Spectrum of the Respiratory Ferment. In yeast and Acetobacter pasteurianum the following photochemical absorption spectrum was thus found: a very high (Soret) band at 432-433 lUfx (€",.M = 156), a strong band at 283 m^{e^^i = 87), and a fainter baud at [590][591][592][593] m/x (e^M = 13.5). There are also weak bands in the green which appear to be different for yeast and Acetobacter (cf.…”

“…There are, however, some claims for the existence of such isomerism. Conant and Bailey (473) found an isorhodoporphyrin which was further studied by Dietz and Werner (591). It differed from rhodoporphyrin in absorption spectrum and HCl number.…”

“…The diagram in Figure 4 gives the relations of the bands as found by Keilin. It is assumed that cytochrome a, which does not react with carbon monoxide, is accompanied by cytochrome as, which has similar absorption bands but reacts with carbon monoxide. To the carbon monoxide compound of the latter, the bands at [590][591][592][593] mju and 432 m^t are ascribed. In all cells studied the relative concentrations of cytochromes a and as were found to be the same {e.g., in the flight muscles of insects), and it is assumed that they are interconvertible.…”

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).
