The chemical nature of bound nicotinic acid

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, ...

Nicotinic acid values by chemical and microbiological methods; effect of hydrogen peroxide and infra-red rays on nicotinic acid.

For comparative purposes the nicotinic acid content of various products has been determined by both chemical and microbiological methods. Along with this comparative study, work has been done on treatments of the extracts and a study of the effects produced as a result of the treatment on the nicotinic acid content previously determined. A survey of the literature discloses that numerous discre...

Application 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...
