Differential role of the two zeta-carotene desaturase paralogs in carrot (Daucus carota): ZDS1 is a functional gene essential for plant development and carotenoid synthesis
(Elsevier, 2020)
Daucus carotais abiennale cropthatdevelopsanedible storageroot.Orange carrots,the mostconsumed cultivar worldwide, accumulate high levels of β-carotene and α-carotene in the storage root during secondary growth. Genes ...
Adding a purple corn extract in rats supplemented with chia oil decreases gene expression of SREBP-1c and retains Δ5 and Δ6 hepatic desaturase activity, unmodified the hepatic lipid profile
(Elsevier, 2018-05)
Flavonoids upregulate gene expression of PPAR-alpha and underregulate the gene expression of SREBP-lc, and their intake increases the plasmatic concentration of n-3 LC-PUFAs. However, the biological mechanisms underlying ...

Monounsaturated fatty acid aerobic synthesis in Bradyrhizobium TAL1000 peanut-nodulating is affected by temperature
(Wiley, 2013-03)
Aims: The aim of this work was to clarify the mechanism of monounsaturated fatty acid (MUFA) synthesis in Bradyrhizobium TAL1000 and the effect of high temperature on this process. Methods and Results: Bradyrhizobium TAL1000 ...
A Novel Sterol Desaturase-Like Protein Promoting Dealkylation of Phytosterols in Tetrahymena thermophila
(American Society For Microbiology, 2011-01)
The gene TTHERM_00438800 (DES24) from the ciliate Tetrahymena thermophila encodes a protein with three conserved histidine clusters, typical of the fatty acid hydroxylase superfamily. Despite its high similarity to sterol ...
Enhancement of carotenoid production by disrupting the C22-sterol desaturase gene (CYP61) in Xanthophyllomyces dendrorhous
(2012)
Background: Xanthophyllomyces dendrorhous is a basidiomycetous yeast that synthesizes astaxanthin, which is a carotenoid with a great biotechnological impact. The ergosterol and carotenoid synthesis pathways are derived ...
The cytochrome b(5) dependent C-5(6) sterol desaturase DES5A from the endoplasmic reticulum of Tetrahymena thermophila complements ergosterol biosynthesis mutants in Saccharomyces cerevisiae.
(Elsevier Science Inc, 2012-09)
Tetrahymena thermophila is a free-living ciliate with no exogenous sterol requirement. However, it can perform several modifications on externally added sterols including desaturation at C5(6), C7(8), and C22(23). Sterol ...
Does genetic variation in the Δ6-desaturase promoter modify the association between α-linolenic acid and the prevalence of metabolic syndrome?
(2009)
Background: Eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA) are associated with protection against components of the metabolic syndrome, but the role of α-linolenic acid (ALA), the metabolic precursor of EPA and ...
