摘要:
Abstract“Heteroenzyme” is the term applied to proteins of different origin that differ in their physical, chemical, and biochemical properties, but have the same biological action. Enzymes that have the same origin, and consist of very similar, but distinguishable proteins have been named “isozymes” [*]; they may also be designated as “multip

摘要:
AbstractMicro‐organisms form enzymes that catalyze many reactions which are difficult to carry out in the laboratory or which involve many steps. Enzymes even react with substances which are normally foreign to them. The frequently high stereospecificity of microbiological reactions is of particular significance. The most important types of reactions are: hydroxylations, dehydrogenations (oxidations), and hydrogenations (reductions), cleavage of ester and C‐C bonds, and transglycosidations. The variety of the compounds converted is extremely gr

摘要:
AbstractInverse polarographic and voltammetric methods are surveyed. The electrochemical determination procedure is carried out by current reversal after electrolytic concentration on a working electrode. Analyses in the nanogram (ng) region (10−9g.) are possible because the sensitivity is increased by a factor of 100 to 1000 in comparison with the usual polarographic and voltammetric methods. These methods are, therefore, of particular interestin trace analysi

摘要:
AbstractA comparison of known types of converters used for the synthesis of ammonia, and an evaluation of their respective advantages and disadvantages are given. A new type of converter is described, in which catalyst contact beds alternate with heat exchange regions. This arrangement permits both close control of the operating temperature at or near optimum conditions and utilization of the excess heat of reaction for preheating the reaction gases.
