The reduction of cozymase by sodium borohydride.
Cozymase (diphosphopyridine nucleotide, DPN) has been assayed by a variety of biochemical and chemical methods (1). Among the simplest procedures has been the determination of the light absorption of reduced DPN at 340 rnp after reduction by sodium hydrosulfite. Since special precautions are required to remove completely the excess reducing agent which absorbs in this region, it appeared advant...
متن کاملReduction of Chlorophyllides, Chlorophylls and Chlorophyll Derivatives by Sodium Borohydride.
Sodium borohydride is a well known reducing agent. In methanol at room temperature formyl and keto groups are readily reduced to alcohol groups, while ester and carboxyl groups, carbon-carbon and carbon-nitrogen double bonds are only reduced with difficulty (2, 17). Of the groups present in chlorophyll b the C3 formyl and the C9 keto groups should be amenable to reduction, while the C2 vinyl an...

abstract while task-based instruction is considered as the most effective way to learn a language in the related literature, it is oversimplified on various grounds. different variables may affect how students are engaged with not only the language but also with the task itself. the present study was conducted to investigate language and task related engagement on the basis of the task typolog...

15 صفحه اولInactivation of Tetracycline with Sodium Borohydride.
Recently we reported on the rapid inactivation of tetracycline by use of cupric-morpholine complex (Kaplan, Lannon, and Buckwalter, J. Pharm. Sci., 64, 163, 1965). This degradation procedure is used as part of an assay technique for kanamycin in the presence of tetracycline. We have since found that sodium borohydride (Metal Hydrides Inc., Beverly, Mass.) can substitute for cupric-morpholine co...
