It has been demonstrated that when isolated chloroplasts are illuminated in the presence of aqueous solutions of certain oxidants, oxygen evolution occurs (2, 5, 6, 7, 8, 13). Provided stoichiometric relationships between the reactants and products prevail, the reaction rate can be measured in terms of oxygen production or in terms of changes in the concentration of whatever other molecular or ...

Water is essential to the life of every living organism. The water used by consumer must be safe for preservation his health. objective this study was assess quality well in households city Korhogo. To do this, samples were taken from wells different households. Parameters such as pH, temperature, electrical conductivity and total dissolved solids measured at sampling sites. Nitrates ammonium d...

We describe a fixed-time-interval, kinetic inhibition method, with use of a competitive inhibitor (l) of the urease/glutamate dehydrogenase reaction to increase the "apparent" Michaelis constant by a factor of (1 + [l]lKl). This allows greater flexibility in selecting an appropriate sample dilution for kinetic determinations of urea in serum (i.e., [S]lKm ratio). Nine compounds were screened as...

Objective: Alcea genus belongs to Malvaceae family and this is represented by 85 taxa in the world 21 Flora of Turkey.The flowers contain plenty mucilage are used for treatment respiratory diseases such as asthma cough.Alcea dissecta known ‘Govik, Hiro, Hero’ Turkey, leaves species have been asthma,injury, colds, gastrointestinal Turkey. To best our knowledge, there no report on effect extracti...

Sensitivity to low concentrations of desaspidin (5 x 10(-7)m) sharply distinguishes the photophosphorylations associated with the photooxidation of water from all other types of photophosphorylation by isolated chloroplasts. Contrary to recent reports in the literature, the effects of desapidin were not altered by changes in the redox conditions as influenced by the concentration of ascorbate a...

The oxidation of the o-aminophenols, 2-amino-1-fluorenol, 3hydroxy-4-aminobiphenyl, and of o-aminophenol itself by cytochrome c and cytochrome oxidase in vitro has been shown to yield colored oxidation products with characteristic visible absorption spectra (2). The present paper is concerned with the identification of these products by chemical synthesis. The oxidation products of 3-hydroxy-4-...

Inrat liver microsomal fractions oxidation of adrenaline was effected by superoxide anion radicals (A), whereas cytochrome c, 2,6-dichlorophenol-indophenol and ferricyanide accepted electrons from NADPH-specific filavoprotein only directly. Nitro Blue Tetrazolium was reduced both by 02and by tbe direct acceptance of electrons. Elevation ofpH and addition of menadione shift the Nitro Blue Tetraz...
