THE BACTERIAL OXIDATION OF NICOTINIC ACID [PDF]

open access: hybridJournal of Biological Chemistry, 1957
N-Formylmaleamic acid, a probable intermediate in the bacterial metabolism of nicotinic acid, has been synthesized by photoisomerization of its transisomer, N-formylfumaramic acid. The compound previously reported to be N-formylmaleamic acid has been shown to be N-formylfumaramic acid.

A New Method for the Determination of Nucleic Acid Using an Eu3+– nicotinic Acid Complex as a Resonance Light Scattering Probe [PDF]

open access: yesMolecules, 2008
This study found that in Tris-HCl buffer, the resonance light scattering (RLS) intensity of the Eu3+-nicotinic acid system can be greatly enhanced by nucleic acids and the enhanced intensity is proportional to the concentration of nucleic acid in the ...

Nicotinic Acid Metabolism

open access: hybridJournal of Biological Chemistry, 1969
Abstract An enzyme that catalyzes the reversible hydroxylation of nicotinic acid to 6-hydroxynicotinic acid has been purified from extracts of a nicotinic acid-fermenting clostridium. The enzyme appears to be a flavin adenine dinucleotide-containing non-heme iron protein and utilizes triphosphopyridine nucleotide as the ultimate electron acceptor.

Solution thermodynamics of aqueous nicotinic acid solutions in presence of tetrabutylammonium hydrogen sulphate [PDF]

open access: yesJournal of the Serbian Chemical Society, 2013
In this study we investigated the effects of tetrabutylammonium hydrogen sulphate (Bu4NHSO4) on the solute-solute and solute-solvent interactions in the aqueous solutions of nicotinic acid in terms of apparent molar volumes (φV), standard partial ...

Arachidonic Acid as a Possible Negative Feedback Inhibitor of Nicotinic Acetylcholine Receptors on Neurons [PDF]

open access: yes, 1995
Neuronal acetylcholine receptors, being highly permeable to calcium, are likely to regulate calcium-dependent events in neurons. Arachidonic acid is a membrane-permeant second messenger that can be released from membrane phospholipids by phospholipases ...
