Bound Nicotinic Acid in Dietary Wheaten Products.
In cereals, nicotinic acid occurs mainly in a bound form, niacytin, which is nutritionally unavailable to certain bacteria and mammals (Kodicek & Wilson, 1960). Most published findings relating to nutritional availability have been on rats and pigs, and the results have been in agreement with microbiological assays (Braude, Kon, Mitchell & Kodicek, 1955 ; Kodicek, Braude, Kon & Mitchell, 1956, ...
متن کاملInsulin Signaling in Liver and Adipose Tissues in Periparturient Dairy Cows Supplemented with Dietary Nicotinic Acid.
The glucose homeostasis in dairy cattle is very well controlled, in line with the metabolic adaptation during the periparturient period. Former studies showed that nicotinic acid (NA) lowered plasma non-esterified fatty acids (NEFA) concentrations and increased insulin sensitivity in dairy cows. Thus, the purpose of this study was to investigate whether the expression of proteins involved in he...
متن کاملNicotinic acid metabolism. II. The isolation and characterization of intermediates in the fermentation of nicotinic acid.
6-Hydroxynicotinic acid was demonstrated to be the first intermediate in the degradation of nicotinic acid by a clostridium. In the presence of pyruvate, other intermediates accumulated; two of these were identified, one as 1,4,5,6tetrahydro-6-oxonicotinic acid, and the other as a!-methyleneglutaric acid. The pathways for nicotinic acid degradation may be considered as involving successive oxid...
متن کاملApplication of Nicotinic Acid Functionalized Chlorosulfonic Acid as a Green Catalyst for the Synthesis of Bis(2-methyl-1Hindole)Derivatives
3-Carboxy-1-sulfopyridin-1-ium chloride ([CPySO3H]+Cl-) as a novel ionic organocatalyst for thecondensation of aldehydes and 2-methylindole to synthesize bis(2-methyl-1H-indole) derivatives inacetonitrile at room temperature has been developed. Some tetrakis (2-methyl-1H-indole)derivatives have also been synthesized by the reaction of 2,2'-(butane-1,4-diylbis(oxy))dibenzaldehyde and 2-methylind...
متن کاملThe Microbiological Determination of Nicotinic Acid, Nicotinamide, and Nicotinuric Acid
The nicotinic acid assay most generally satisfactory is the Lactobacillus arabinosus procedure (1, 2) as regards sensitivity and non-interference from other compounds. However, this organism responds to nicotinamide and nicotinuric acid as well as to nicotinic acid. Gaines and Stahly (3) have proposed the use of Leuconostoc mesenteroides for the assay of several members of the vitamin B complex...
