Metabolism of nicotinamide and nicotinic acid in Corcyra cephalonica St

Comparative metabolism of nicotinamide and nicotinic acid in mice.

Metabolism of nicotinamide and nicotinic acid in Neurospora crassa.

Nicotinic acid is outstanding among the B vitamins in that its metabolic fate has been very extensively investigated. These studies, however, have been carried out mostly in higher animals, and they have revealed that (i) N'-methylnicotinamide is, in general, the major end-product of the metabolism of both nicotinic acid and nicotinamide; (ii) nicotinuric acid, the glycine conjugate of nicotini...

Nicotinic acid and nicotinamide metabolism in ascites cells in vitro.

The studies reported here are primarily concerned with the metabolism of vitamin-containing nucleotides in intact cells. Holzer, Friedrich, and Grisebach (I) have reported that the Ehrlich ascites cells incorporated nicotinic acid-C4 slowly into nicotinamide adenine dinucleotide. Since, under the same conditions, nicotinamide-Cl4 was rapidly incorporated into nicotinamide adenine dinucleotide, ...

Effect of Tephrosia purpurea Extract on Fecundity Of Corcyra cephalonica (st.)

The naturally occurring allilochemics play a promising role in insect control by deterring insect feeding by their effects as insect growth regulators, as antihormones or as insecticides. Effect of Tephrosia purpurea extracts on reproductive ability i.e. fecundity was reduced at more than 40.08 %. There is reduction in hatching percentage also. It may be due to reduced juvenile hormone titre wh...

The metabolism of radioactive nicotinic acid and nicotinamide.

The use of isotopes as tracers, both stable and radioactive, has become a well established technique for the study of intermediate metabolism of many compounds of biological importance. Recently the synthesis of radioactive nicotinic acid and nicotinamide (with Cl4 in the carboxyl group) has been reported by Murray, Foreman, and Langham (1). In this paper the gross metabolism of radioactive nic...
