A Wagner–Meerwein‐Like Rearrangement Generates a Vinyl Group in the Biosynthesis of the Polychlorinated Lipopeptides Fischerazoles

Angewandte Chemie, EarlyView.
The fischerazoles, unusual cyanobacterial chlorinated lipopeptides are reported. During their biosynthesis, a linear fatty acyl‐acyl carrier protein (ACP) precursor is rearranged through the action of the S‐adenosyl‐methionine (SAM)‐dependent methyltransferase FshF, to generate a pendant vinyl group.

Tannin, protein contents and fatty acid compositions of the seeds of several Vicia L. species from Turkey

Grasas y Aceites, 2010
The seedoils of six Vicia species (Leguminosae) were investigated for their protein, tannin contents and fatty acid compositions. The protein contents of the seeds were found to be between 21.87%-31.33%.

Mitochondrial 2,4-dienoyl-CoA reductase deficiency in mice results in severe hypoglycemia with stress intolerance and unimpaired ketogenesis. [PDF]

PLoS Genetics, 2009
The mitochondrial beta-oxidation system is one of the central metabolic pathways of energy metabolism in mammals. Enzyme defects in this pathway cause fatty acid oxidation disorders.

Fatty acid desaturation in lung: inhibition by unsaturated fatty acids

Journal of Lipid Research, 1980
The activity of the enzyme system involved in desaturation of palmitic and stearic acid has been examined in lungs of rats fed fat-free diets supplemented either with 4% safflower oil (controls) or 4% tripalmitin (essential fatty acid (EFA) deficient) both in vivo and in vitro in lung slices.

Super‐Multiplexed Label‐Free Raman Imaging Uncovers Novel Testicular Metabolic Couplings for Residual Body and Spermatogonial Differentiation

Advanced Science, EarlyView.
Super‐multiplexed Label‐free Raman Imaging (SLRI) enables 2D/3D metabolic mapping of intact Drosophila testes. Moving beyond descriptive morphology, it establishes a multidimensional tool for tissue metabolic remodeling, and offers a generalizable platform for complex tissue analysis, with implications extending to development and disease. ABSTRACT The

Flavin Catalysts in Organic Synthesis

Angewandte Chemie, EarlyView.
Flavins and their congeners are potent catalysts for organic synthesis inspired by enzymatic transformations. In addition to catalysis in the flavin ground state via covalent intermediates, the excited singlet and triplet states unlock applications including photooxidation, photoreduction, and energy transfer via sensitization.

Atypical Condensation Domains Guide Discovery and Illuminate Biosynthesis of Myxoglucamides Featuring Vinyl‐Substituted, α‐Oxidized γ‐Amino Acids

Angewandte Chemie, EarlyView.
Genome mining of atypical condensation (C) domains leads to the discovery of myxoglucamides, glycolipopeptides featuring an unprecedented vinyl‐substituted, α‐oxidized γ‐amino acid. Biosynthetic studies reveal a discrete C‐domain‐like O‐acyltransferase, a β‐hydroxylation‐dependent chain‐extension checkpoint, and an unusual pathway for γ‐amino acid ...

Metabolic Reprogramming in Glioblastoma Stem Cells Promotes Radiation Resistance Through a H3K18la/USP30/MBOAT2 Axis

Advanced Science, EarlyView.
LDHA‐driven lactate production in mesenchymal glioma stem cells promotes p300‐dependent H3K18 lactylation, activates USP30 transcription, and stabilizes MBOAT2 to remodel phosphatidylethanolamines toward ferroptosis‐resistant PE‐MUFA species. Disrupting this metabolic–epigenetic–lipid circuit enhances ferroptosis and sensitizes glioblastoma to ...

INFLUENCE OF BREED AND SEASON ON THE FATTY ACID COMPOSITION OF GOAT MILK [PDF]

Scientific Papers Series : Management, Economic Engineering in Agriculture and Rural Development, 2023
It was analyzed how the content of fatty acids in the milk of Saanen goats and goats of Ukrainian breeding depended on the breed of goats. The experiment was based on a comparison of the content of fatty acids in the milk of 20 goats, of which 10 were ...
