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 کاملInactivation 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...
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...
متن کاملDynamic Modeling of Hydrogen Generation via Hydrolysis of Sodium Borohydride
This paper deals with the dynamic modeling of a hydrogen production system using gPROMS. The model includes mass balances, liquid-gas equilibrium relations, mass transfer laws and kinetic reaction equations. The initial reaction mixture is a sodium borohydride solution that reacts via a self-hydrolysis mechanism in the presence of water. The behavior of this system was measured in terms of prod...
متن کاملDynamics of dihydrogen bonding in aqueous solutions of sodium borohydride.
Dihydrogen bonding occurs between protonic and hydridic hydrogens which are bound to the corresponding electron withdrawing or donating groups. This type of interaction can lead to novel reactivity and dynamic behavior. This paper examines the dynamics experienced by both borohydride and its dihydrogen-bound water solvent using 2D-IR vibrational echo and IR pump-probe spectroscopies, as well as...
