In this paper the writer employs complex Riemannian Geometry and defines the absolute interval between two points as consisting of a real part and an imaginary part. Two postulates (I) and (II) are used: the first may be called law of gravitation and electro-magnetism; the second equation of motion. In the absence of electromagnetic phenomena the theory reduces practically to Einstein's theory.

The effects of copper and zinc ionsupon the precipitation of barium sul-phate have been noted for a long time.However,the results published wereeither not systematic(3,4b,5,6)or obtained under conditions apart fromusual analytical practice(7,8).Thus,it seems necessary to investigate thissubject in more detail by the usual methods of determination.The presentcommunication reports(a)the effect of various amounts of cupric and zincions and(b)the influence of different acidities during precipitation in thepresence and absence of zinc ions.It is found that the interference of copper in the determination of sulphuras barium sulphate up to a ratio of 20:1 for Cu:S is negligible.The deviationsof the results obtained from theoretical values are all within ±2‰(see Table1),and do not show any regularity with the amount of copper added.The presence of zinc ions alone gives satisfactory results(slightly lowerthan theoretical values).As the amount of zinc ions in solution increases,thedeviations become somewhat wider(Table 2).The low results are presumedto be due to(1)the formation of soluble zinc-sulphate complex,which holdsa part of sulphate in solution,and/or(2)diverse ion effect.In the presenceof zinc ions,introducing hydrochloric acid up to 0.1 N before precipitationcauses essentially the same errors as if hydrochloric acid were absent(cf.Tables2 and 3),while at and beyond 0.2 N positive errors are obtained.A spectrographic examination of the precipitates reveals that zinc doescoprecipitate with barium sulphate,though only to a slight extent.The amountof zinc coprecipitated decreases with the increase of the acidity of the solutionfrom which the precipitate is thrown down.

(1) Sodium salt of reduced codehydrogenase I has been obtained in good yield as a dry powder from codehydrogenase I by reduction with alcohol and alcohol dehydrogenase. This preparation was stable for at least 5 months when kept dry at -15℃. (2) The properties of the particle-bound codehydrogenase I cytochrome reductase system in heart muscle preparation were found to differ considerably from those of the soluble enzyme as obtained by Mahler et al. Among other things, the affinity for cytochrome c of the particle-bound enzyme is much greater than the soluble enzyme. The Michaelis constant for cytochrome c of the former is only one twelfth of that of the latter.(Fig. 2A). (3) With either oxygen or excess cytochrome c as electron acceptor, it was found that the overall activity, in terms of rate of oxygen consumption or cytochrome c reduction, when both succinate and reduced codehydrogenase I were oxidized simultanously, did not represent the sum of the rates of oxidation when these two substrates were separately oxidized but equalled only the faster of the two separate oxidation rates(Fig. 5, Tables 1, 2). If 2,6-dichlorophenol indophenol was used as the electron acceptor, the overall rate of simultaneous oxidation of these two substrates was found to equal exactly the sum of the rates of separate oxidation(Table 3). (4) When either oxygen or excess cytochrome c was used as the electron acceptor, reduced codehydrogenase I and succinate each inhibited the rate of oxidation of the other(Figs 4, 6 & 7). Evidence has been presented to show that the inhibition of succinate oxidation by reduced codehydrogenase I is not due to the accumulation of oxaloacetate. (5) When malonate was also added to the reaction mixture, succinate no longer produced any inhibition of the oxidation of reduced codehydrogenase I(Fig. 8). (6) It is therefore concluded that in heart muscle preparation both succinate and reduced codehydrogenase I are oxidized by cytochrome c through a common, velocity limiting factor. This is in accordance with the view previously reached by some workers from studies on the action of certain inhibitors. However, it should be noted that in our experiments no agents which might produce any conceivable change in the colloidal structure of the enzyme system has been employed. (7) It should be emphasized that our results clearly show that great caution must be exercised in drawing conslusion on the role an enzyme might play in a complex enzyme system from studies of the properties of a solubilized enzyme. (8) It is believed that the competition of two enzyme systems for a common linking factor as demonstrated in this report has provided a new method for studies on the mutual relations of two or more enzyme systems.

(一)本報告提供了一個從輔酶Ⅰ,用酶還原法製備還原輔酶Ⅰ的方法。我們所製得的還原輔酶Ⅰ鈉鹽乾粉,可以在低温保存數月而不被氧化。 (二)與心肌製劑中顆粒相結合的輔酶Ⅰ細胞色素還原酶系,和用乙醇抽出的水溶性的輔酶Ⅰ細胞色素還原酶的性質頗不相同。其中比較重要的不同點是對於細胞色素c的親力,前者遠大於後者,其米氏常數僅約為後者的十二分之一。 (三)用一心肌顆粒製劑作為材料,無論用氧或過量之細胞色素c作為氫受體,還原輔酶Ⅰ與琥珀酸同時氧化時的總速度,不等於二者分別氧化時速度之和,而僅等於其中氧化較快者單獨氧化時之速度。但如用[2,6]二氯靛酚作為氫受體時,二者共同氧化時之總速度完全等於二者分別氧化時速度的和。 (四)當用氧或過量之細胞色素c作為氫受體時,琥珀酸與還原輔酶Ⅰ能彼此互相抑制對方氧化的速度。有足夠的實驗材料說明,還原輔酶Ⅰ對於琥珀酸氧化的抑制,不是由於草醯乙酸聚集的緣故。 (五)如果在反應混合物中同時含有琥珀酸脫氫酶的專一抑制劑,丙二酸,則琥珀酸對於還原輔酶Ⅰ氧化作用的抑制即被解除。 (六)根據以上的實驗結果,可以認為,還原輔酶Ⅰ及琥珀酸先通過一個共同的因子與細胞色素c作用。這個共同的因子在一般情形之下,也是...
