hydrogenation

The addition of hydrogen to another compound, usually an unsaturated organic compound. Unsaturated oils are hydrogenated to form margarine.

Noun1.hydrogenation - a chemical process that adds hydrogen atoms to an unsaturated oil; "food producers use hydrogenation to keep fat from becoming rancid"

In our study, the concentration of C18:0 (the product of the terminal biohydrogenation of UFA) and the ratio of IPSSFA/IPSUFA and IPSSFA/IPSFA in the SAT of lambs fed the experimental diets decreased when compared to the control diet (contrast 0.
Although the relationship between consumption of fatty acid and their recovery in the animals' tissues is complex in ruminants due to the ruminal biohydrogenation, nevertheless, nutrition is a key factor to enhance beneficial fatty acid portions in ruminant-source products.
The lower proportion of stearic acid found in the meat of grain-fed animals can be explained by the decrease in ruminal biohydrogenation (Aharoni, Orlov, & Brosh, 2004).
In addition, 5beta-cholestanone, an oxidation product of 5beta-coprostanol formed via biohydrogenation of cholesterol, decreased by 5-fold in diazinon-treated female mice, which was not statistically significantly altered in male mice.
The conjugated linoleic acid CLA is formed by rumen biohydrogenation of intermediate linoleic acid (Lee, 2013) and if the biohydrogenation is not complete, it may be absorbed by the gut epithelium and will be part of the animal fat (Ladeira & Oliveira, 2007).
Reticulo-rumen biohydrogenation and the enrichment of ruminant edible products with linoleic acid conjugated isomers.
11-Octadecenoic acid and C18:2 trans- 10, cis-12 CLA are synthesized in the rumen as a transient intermediate in the process of biohydrogenation of linoleic acid [18].
However it is more difficult to produce animal products with increased levels of UFA in ruminants because of biohydrogenation of dietary UFA by ruminal microorganisms.
Biohydrogenation of unsaturated fatty acids by rumen bacteria.
AbstractTrans fatty acids (TFA) are produced either by hydrogenation of unsaturated oils or by biohydrogenation in the stomach of ruminant animals.
