The biohydrogenation of alpha-linolenic acid and oleic acid by rumen micro-organisms.
1. alpha-[U-(14)C]Linolenic acid was incubated with the rumen contents of sheep and the metabolic products were characterized by thin-layer chromatography, gas-liquid chromatography and absorption spectroscopy in the ultraviolet and infrared. 2. A tentative scheme for the biohydrogenation route to stearic acid is presented. The main pathway is through diconjugated cis-cis-cis-octadecatrienoic a...
متن کاملOleic acid versus linoleic and α-linolenic acid. different effects on Ca2+ signaling in rat thymocytes.
BACKGROUND Oleic acid is the principal fatty acid of olive oil composition and is reported to play a crucial role in its healthy aspects. However, the detailed mechanism of action is poorly understood. AIMS This study aims to elucidate the role of oleic acid in calcium signaling in rat thymocytes, in comparison to linoleic and linolenic acid. METHODS Fatty acids were applied to thymocytes i...
متن کاملMicrobial biohydrogenation of oleic acid to trans isomers in vitro.
Ruminant products are significant sources of dietary trans fatty acids. Trans fatty acids, including various conjugated linoleic acid isomers, have been shown to act as metabolic modifiers of lipid metabolism. Trans fatty acids originate from biohydrogenation of dietary unsaturated fatty acids by gut microbes; however, the exact synthetic pathways are unclear. It was our goal to examine the bio...
متن کاملHumans are more sensitive to the taste of linoleic and α-linolenic than oleic acid.
Health concerns have led to recommendations to replace saturated fats with unsaturated fats. However, addition of unsaturated fatty acids may lead to changes in the way foods are perceived in the oral cavity. This study tested the taste sensitivity to and emulsion characteristics of oleic, linoleic, and α-linolenic acids. The hypothesis tested was that oral sensitivity to nonesterified fatty ac...
متن کاملEffect of unsaturated C18 fatty acids (oleic, linoleic and α-linolenic acid) on ruminal fermentation and production of fatty acid isomers in an artificial rumen
The objective of this study was to examine the effect of oleic (OA), linoleic (LA) and α-linolenic (ALA) acid used as supplements (3.5% wt/wt) to a diet containing 80% lucerne and 20% barley on rumen fermentation and lipid metabolism in an artificial rumen (Rusitec). The experiment lasted 12 days with 6 days of stabilization period. The fatty acid (FA) supplementation to a mixed diet did not af...
