Diatoms synthesize sterols by inclusion of animal and fungal genes in the plant pathway [PDF]

, 2020
Diatoms are ubiquitous microalgae that have developed remarkable metabolic plasticity and gene diversification. Here we report the first elucidation of the complete biosynthesis of sterols in the lineage.

Shelf Life Quality and Bioactive Constituents of Virgin Olive Oil Affected by Packaging Type and Storage Period [PDF]

New Valley Journal of Agricultural Science, 2023
One of the few oils is virgin olive oil, consumed without any chemical treatment. It is likely that the actual storage period and packing type reflect actual changes in the virgin olive oil matrix.

Plant-based beverages as good sources of free and glycosidic plant sterols [PDF]

, 2017
To address the ever-growing group of health-conscious consumers, more and more nutritional and health claims are being used on food products. Nevertheless, only very few food constituents, including plant sterols, have been appointed an approved health ...

Determination of sterols and triterpenic dialcohols in olive oils using HPLC separation and GC analysis. Standardization of the analytical method.

Grasas y Aceites, 1997
A method is developed for the analysis of sterols together with triterpenic alcohols (erythrodiol and uvaol) in vegetable oils. The method involves obtention of the unsaponifiable matter, isocratic HPLC separation with refractive index detector ...

A dietary sterol trade-off determines lifespan responses to dietary restriction in Drosophila melanogaster females

eLife, 2021
Diet plays a significant role in maintaining lifelong health. In particular, lowering the dietary protein: carbohydrate ratio can improve lifespan. This has been interpreted as a direct effect of these macronutrients on physiology.

Mutations in UDP-Glucose:Sterol Glucosyltransferase in Arabidopsis Cause Transparent Testa Phenotype and Suberization Defect in Seeds [PDF]

, 2009
In higher plants, the most abundant sterol derivatives are steryl glycosides (SGs) and acyl SGs. Arabidopsis (Arabidopsis thaliana) contains two genes, UGT80A2 and UGT80B1, that encode UDP-Glc:sterol glycosyltransferases, enzymes that catalyze the ...
