Bile acids: Lipase-catalyzed synthesis of new hyodeoxycholic acid derivatives
(Elsevier Science Inc, 2018-12)
In this work we present an efficient, environmentally friendly approach to the synthesis of a series of hyodeoxycholic acid derivatives applying Biocatalysis. Fifteen acetyl and ester derivatives, twelve of them new, were ...
Performance and Economic Viability of Broiler Chickens Fed with Probiotic and Organic Acids in an Attempt to Replace Growth-Promoting Antibiotics
(Facta-fundacio Arnco Ciencia Tecnologia Avicolas, 2019-01-01)
The aim of this study was to evaluate diets supplemented with probiotic (Bacillus amyloliquefaciens) and organic acids (lactic, acetic and butyric acid) in attempt to replace the antibiotics and anticoccidial (avilamycin ...
Acetylation of bacterial cellulose catalyzed by citric acid: Use of reaction conditions for tailoring the esterification extent
Bacterial cellulose (BC) nanoribbons were partially acetylated by a simple direct solvent-free route catalyzed by citric acid. The assay of reaction conditions within chosen intervals (i.e. esterification time (0.5–7 h), ...
Plasma Arachidonic Acid Influences Insulin-Stimulated Glucose Uptake in Healthy Adult Women
Background: Fatty acids can modulate lipid metabolism, this is related to insulin resistance (IR). This study evaluated the relationship of plasma fatty acid profile with IR, fuel oxidative metabolism and plasma lipid ...
Production of biodiesel from acid oil using sulfuric acid as catalyst: Kinetics study
(Oxford University Press, 2011-03)
