Ferulic Acid in Cereals – a Review

Boz H. (2015): Ferulic acid in cereals – a review. Czech J. Food Sci., 33: 1–7. Phenolic acids represent the most common form of phenolic compounds in the cereal grain and many other plants. The phytochemical ferulic acid is found in the leaves and seeds of many plants, but especially in cereals. It is the most abundant phenolic acid in common cereals, representing up to 90% of total phenolic c...

Experience with Nicotinic Acid

Nicotinic Acid Metabolism

Previous reports from this laboratory have described the isolation of 6-hydroxynicotinic acid and 6-0x0-1 ,4,5,6-tetrahydronicotinic acid from the reaction media of a clostridial species grown on nicotinic acid (1). Bn enzyme that catalyzes the reversible oxidation of nicotinic acid to HNA’ has been purified from extracts of this microorganism (2). Since fortified crude extract of this Clostrid...

Nicotinic 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...
