The author focuses on the biological significance of ω-oxidation of fatty acids. Early studies revealed that there is a subsidiary pathway for β-oxidation of fatty acids when β-oxidation is blocked. Many studies demonstrated that the ω-oxidation serves to provide succinyl-CoA for the citric acid cycle and for gluconeogenesis under conditions of starvation and diabetes. Acylglucosylceramides whi...

The aim of this study was to determine whether citric acid adsorbed onto cobalt ferrite (CoFe2O4) nanoparticles (NPs) influences the bioavailability of their constituents Co and Fe. Dissolution of Co and Fe was assessed by two measures: (i) in aqueous suspension using chemical analysis, prior to application onto the food of test organisms; and (ii) in vivo, measuring the bioavailability in the ...

As early as 1897 the oxidative bromination of citric acid to form a brominated acetone derivative, presumably principally pentabromoacetone, was adapted to the quantitative determination of citrate (1). Most subsequent procedures have been based on the same reaction. Among the more recently described procedures are those of Pucher (2) and of Goldberg and Bernheim (3). These methods, with minimu...

Problem statement: The aim of this study was to investigated the effects of adding citric acid and microbial phytase supplementation (Natuphos) on growth performance and carcass characteristics of broiler chickens fed corn soybean meal base diets. Approach: The experiment included nine treatments with 10 birds in each replicate using a 3×3 factorial design for two main factors of citric acid (0...
