Plant phloem sterol content: forms, putative functions, and implications for phloem-feeding insects

open access: yesFrontiers in Plant Science, 2013
All eukaryotes contain sterols, which serve as structural components in cell membranes, and as precursors for important hormones. Plant vegetative tissues are known to contain mixtures of sterols, but very little is known about the sterol composition of ...

Influence of Regulated Deficit Irrigation on Arbequina’s Crop Yield and EVOOs Quality and Sensory Profile

open access: yesAgronomy, 2022
Regulated deficit irrigation in super-high-density (SHD) olive orchards is a well-known strategy to save water and control plant vigor, without decreasing fruit or oil yield.

Selective sterol accumulation in ABCG5/ABCG8-deficient mice

open access: yesJournal of Lipid Research, 2004
The ATP binding cassette (ABC) transporters ABCG5 and ABCG8 limit intestinal absorption and promote biliary secretion of neutral sterols. Mutations in either gene cause sitosterolemia, a rare recessive disease in which plasma and tissue levels of several

Microwave-Assisted Saponification Method Followed by Solid-Phase Extraction for the Characterization of Sterols and Dialkyl Ketones in Fats

open access: yesFoods, 2021
Unlike other fields, the methods routinely applied for fats and oils are still tied to traditional, time- and solvent-consuming procedures, such as saponification, column chromatography and thin-layer chromatography.

Evidence of late Quaternary environmental change in a continental east Antarctic lake from lacustrine sedimentary pigment distributions [PDF]

open access: yes, 2005
A sediment core from Progress Lake, one of the oldest lacustrine sequences in East Antarctica, contains distinct zones dating from a previous interglacial (most likely Marine Isotope Stage 5e, c.

Effects of diet and metamorphosis upon the sterol composition of the butterfly Morpho peleides

open access: yesJournal of Lipid Research, 2006
Whole body sterol metabolism in insects has seldom been studied. We were able to design an appropriate study at a butterfly farm in Belize. We collected six larvas of butterfly (Morpho peleides), their food (leaves of Pterocarpus bayessii), and their ...

Cholesterol sulfate fluidizes the sterol fraction of the stratum corneum lipid phase and increases its permeability

open access: yesJournal of Lipid Research, 2022
Desulfation of cholesterol sulfate (CholS) to cholesterol (Chol) is an important event in epidermal homeostasis and necessary for stratum corneum (SC) barrier function.

Sterol content of the Myxomycetes Physarum polycephalum and P. flavicomum

open access: yesJournal of Lipid Research, 1976
The sterol content of two Myxomycetes, Physarum polycephalum and P. flavicomum has been examined. The sterols of the two species are apparently identical, the two major sterols in each being poriferasterol and 22-dihydroporiferasterol.

Tetraploid Wheats: Valuable Source of Phytosterols and Phytostanols

open access: yesAgronomy, 2019
Phytosterols are known as healthy compounds obtained mainly from oilseed crops. Cereals were also studied for their sterols content. Few insights have been devoted to other tetraploid species than emmer and durum wheats.

The TriForC database : a comprehensive up-to-date resource of plant triterpene biosynthesis [PDF]

open access: yes, 2018
Triterpenes constitute a large and important class of plant natural products with diverse structures and functions. Their biological roles range from membrane structural components over plant hormones to specialized plant defence compounds.
