Quantitative Deuterium Isotopic Profiling at Natural Abundance Indicates Mechanistic Differences for Δ12-Epoxidase and Δ12-Desaturase in Vernonia galamensis [PDF]

Journal of Biological Chemistry, 2005
Quantitative (2)H NMR spectroscopy can determine the natural abundance ((2)H/(1)H) ratio at each site of a molecule. In natural products, variation in these values is related to the reaction mechanisms in the pertinent biosynthetic pathway. For the first time, this novel approach has been exploited to probe for mechanistic differences in the ...

Production of eicosapentaenoic acid by application of a delta-6 desaturase with the highest ALA catalytic activity in algae

Microbial Cell Factories, 2018
Dunaliella salina is a unicellular green alga with a high α-linolenic acid (ALA) level, but a low eicosapentaenoic acid (EPA) level. In a previous analysis of the catalytic activity of delta 6 fatty acid desaturase (FADS6) from various species, FADS6 ...

Formation of conjugated Delta(11) Delta(13)-double bonds by Delta(12)-linoleic acid (1,4)-acyl-lipid-desaturase in pomegranate seeds

, 2002
For the biosynthesis of punicic acid (18:3(Delta9Z ,11E ,13Z) ) a (11,14)-linoleoyl desaturase activity has been proposed. To isolate this acyl-lipid-desaturase, PCR-based cloning was used.

Expression of human delta-6-desaturase is associated with aggressiveness of human breast cancer

, 2003
Highly unsaturated fatty acids (HUFAs) are cyto-toxic to cancer cells and generated in the body by desaturation from essential fatty acids, primarily involving delta-6-desaturase.

Enhancing Meat Quality Through Dietary Fiber: Insights Into the Gut Microbiota‐Derived Short‐Chain Fatty Acids‐Muscle Axis

Animal Research and One Health, EarlyView.
Dietary fiber (DF) modulates meat quality through the gut‐muscle axis by reshaping gut microbiota, improving intestinal integrity, reducing inflammation, and regulating muscle metabolism. These mechanisms influence muscle fiber characteristics and post‐mortem biochemistry, thereby enhancing tenderness, juiciness, color, flavor, and nutritional value of

Sensorial and nutritional qualities of muscles from cross‐bred Salers heifers raised on mid‐mountain pasture

JSFA reports, EarlyView.
Abstract Background This study investigated the effects of crossbreeding, finishing system, and muscle type on carcass characteristics, intramuscular fat (IMF), image‐based IMF estimation, fatty acid composition, and meat quality in beef heifers. Charolais × Salers (C × S) and Angus × Salers (A × S) crossbred heifers were finished either on pasture or ...

Macronutrient and micronutrient profiles of meat types: insights into human health and diet

Journal of the Science of Food and Agriculture, EarlyView.
Abstract Despite considerable advances in global health and nutrition, emerging challenges such as population growth, climate change, and limited natural resources continue to threaten food security. Meat remains an essential component of the human diet, supplying high‐quality proteins, essential amino acids, lipids, vitamins, and minerals necessary ...

Effects of short- and long-chain fatty acids on the expression of stearoyl-CoA desaturase and other lipogenic genes in bovine mammary epithelial cells

Animal, 2013
Stearoyl-CoA desaturase (SCD) in the bovine mammary gland introduces a cis-double bond at the Δ9 position in a wide range of fatty acids (FA). Several long-chain polyunsaturated fatty acids (PUFA) inhibit expression of SCD, but information on the effect ...
