Temperature Acclimation of the Picoalga Ostreococcus tauri Triggers Early Fatty-Acid Variations and Involves a Plastidial ω3-Desaturase

Frontiers in Plant Science, 2021
Alteration of fatty-acid unsaturation is a universal response to temperature changes. Marine microalgae display the largest diversity of polyunsaturated fatty-acid (PUFA) whose content notably varies according to temperature.

Isolation of a Delta(5)-fatty acid desaturase gene from Mortierella alpina [PDF]

, 1998
Arachidonic acid (C20:4 Δ5,8,11,14)) is a polyunsaturated fatty acid synthesized by the ?-fatty acid desaturation of di-homo-?-linolenic acid (C20:3 Δ8,11,14)).

Serum Fatty Acids, Desaturase Activities and Abdominal Obesity - A Population-Based Study of 60-Year Old Men and Women. [PDF]

PLoS ONE, 2017
Abdominal obesity is a key contributor of metabolic disease. Recent trials suggest that dietary fat quality affects abdominal fat content, where palmitic acid and linoleic acid influence abdominal obesity differently, while effects of n-3 polyunsaturated

Influence of consumption of high oleic sunflower oil on the biosynthesis of fatty acids in the liver of rats

Journal of Education, Health and Sport, 2022
Background. To determine the effect of consumption of high-oleic sunflower oil on the content and biosynthesis of energy and polyunsaturated (PUFA) fatty acids in rat liver lipids. Methods. Rats received a semi-synthetic fat-free diet in which 5 % or

Three-year tracking of fatty acid composition of plasma phospholipids in healthy children [PDF]

, 2007
Objectives: The fatty acid composition of plasma phospholipids reflects the dietary fatty acid intake as well as endogenous turnover. We aimed at investigating the potential tracking of plasma phospholipid fatty acid composition in children that ...

Structure and Function of Δ9-Fatty Acid Desaturase

Chemical and Pharmaceutical Bulletin, 2019
Δ9-Fatty acid desaturase (Δ9-desaturase) is a rate-limiting enzyme of unsaturated fatty acid biosynthesis in animal cells and specifically introduces a cis-double bond at the Δ9-position of acyl-CoA. Since the chemical structure of fatty acids determines the physicochemical properties of cellular membrane and modulates a broad range of cellular ...

Characterization of an Omega-3 Desaturase From Phytophthora parasitica and Application for Eicosapentaenoic Acid Production in Mortierella alpina

Frontiers in Microbiology, 2018
Omega-3 long-chain polyunsaturated fatty acids (LC-PUFAs) have important therapeutic and nutritional benefits in humans. In the biosynthesis pathways of these LC-PUFAs, omega-3 desaturase plays a critical role.

FADS1 FADS2 gene cluster, PUFA intake and blood lipids in children [PDF]

, 2012
Elevated cholesterol levels in children can be a risk factor for cardiovascular diseases in later life. In adults, it has been shown that blood lipid levels are strongly influenced by polymorphisms in the fatty acid desaturase (FADS) gene cluster in ...

Molecular Cloning and Functional Expression of a Δ9- Fatty Acid Desaturase from an Antarctic Pseudomonas sp. A3.

PLoS ONE, 2016
Fatty acid desaturase enzymes play an essential role in the synthesis of unsaturated fatty acids. Pseudomonas sp. A3 was found to produce a large amount of palmitoleic and oleic acids after incubation at low temperatures. Using polymerase Chain Reaction (

Effect of genotype on estimated indexes of fatty acid metabolism in rabbits

World Rabbit Science, 2014
To analyse the effect of rabbit genotype on fatty acid metabolism, 60 weaned rabbits (30 d old, sex ratio 1:1; 20 New Zealand White, 20 Leprino of Viterbo and 20 rabbits of a Local grey population) were reared in bicellular standard cages.
