Development of Photo‐Biocatalytic Redox System for Asymmetric Synthesis of Optically Active Amines Using Blue Light and Transaminases. A Case Study Toward Mavacamten

Advanced Synthesis &Catalysis, Volume 367, Issue 12, June 26, 2025.
Abstract α‐Chiral amines are versatile building blocks for the asymmetric synthesis of optically pure high‐added‐value chemicals, including pharmaceuticals, agrochemicals, and natural products. Herein, we report a one‐pot, two‐step sequential deracemization of racemic sec‐alcohols to optically enriched primary amines throught a photo‐biocatalytic ...

Effect of grazing pastures with different botanical composition by lambs on rumen fatty acid metabolism and fatty acid pattern of longissimus muscle and subcutaneous fat

Animal, 2007
In order to study the effect of grazing pastures with a different botanical composition on rumen and intramuscular fatty acid metabolism, 21 male lambs were assigned to three botanically different pastures: botanically diverse (BD) (consisting for 65% of

Corn oil supplementation enhances hydrogen use for biohydrogenation, inhibits methanogenesis, and alters fermentation pathways and the microbial community in the rumen of goats.

Journal of Animal Science, 2019
Enteric methane (CH4) emissions is not only an important source of greenhouse gases (GHG), but also a loss of dietary energy in livestock. Corn oil (CO) is rich in UFA with >50% polyunsaturated fatty acids, which may enhance ruminal biohydrogenation of ...

Effects of Slaughter Age on the Quality of Gannan Yak Meat: Analysis of Edible Quality, Nutritional Value, and GC × GC‐ToF‐MS of the Longissimus Dorsi Muscle

Food Science &Nutrition, Volume 13, Issue 6, June 2025.
Gannan yak meat is a natural green organic food with rich nutritional value. However, the slaughter age of Gannan yaks in the market is older and has lower meat quality. The meat quality of Gannan yak aged 2–4 years is the best, and the content of monounsaturated fatty acids and polyunsaturated fats is the highest.

Feeding heat-oxidized oil to dairy cows affects milk fat nutritional quality

Animal, 2018
Heating oil and oilseeds results in oxidation products that affect ruminal biohydrogenation of polyunsaturated fatty acids, altering milk fatty acids profile, and could be transferred to milk. An experiment was conducted to investigate the effects of oil

The ruminal ratio of trans-10/trans-11 fatty acids obtained in vitro reflects in vivo values and strongly depends on the diet of the donor cow [PDF]

, 2009
Composition of fatty acids (FA) of ruminant products has a potential impact on human health. Among them, trans FA, which are intermediates of the ruminal biohydrogenation of dietary unsaturated FA, deserve interest, in particular trans-10 and trans-11 ...

Effect of toasting and decortication of oat on rumen biohydrogenation and intestinal digestibility of fatty acids in dairy cows.

Journal of Dairy Science, 2020
This experiment quantified the effect of decorticated and toasted oat (Avena sativa L.) on fatty acid (FA) supply, ruminal biohydrogenation (BH) of FA, and intestinal digestibility of FA in 4 ruminal and intestinal cannulated Danish Holstein cows ...

Recycling Agricultural Waste: Sustainable Solutions for Enhancing Livestock Nutrition

Veterinary Medicine and Science, Volume 11, Issue 3, May 2025.
The increasing demand for sustainable agricultural practices prompts a reevaluation of feeding strategies in ruminant nutrition. Agricultural waste, often viewed as a by‐product, presents a promising opportunity to enhance the sustainability of livestock production systems.

Influence of lipid supplementation on milk components and fatty acid profile

Revista Brasileira de Zootecnia
The objective of this study was to evaluate the effects of different lipid sources in diets for lactating cows on milk yield and composition, conjugated linoleic acid (CLA) content, and fatty acid profile in the milk fat.

Effects of oil and natural or synthetic vitamin E on ruminal and milk fatty acid profiles in cows receiving a high-starch diet [PDF]

, 2012
Among trans fatty acids, trans-10,cis-12 CLA has negative effects on cow milk fat production and can affect human health. In high-yielding dairy cows, a shift from the trans-11 to the trans-10 pathway of biohydrogenation (BH) can occur in the rumen of ...
