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 ...

Modeling Softening Kinetics at Cellular Scale and Phytochemicals Extractability in Cauliflower under Different Cooking Treatments

open access: yesFoods, 2021
The effects induced by heat on Depurple and Cheddar (Brassica oleracea L. var. botrytis) during boiling, steaming, and sous-vide were investigated to elucidate the role of the basic cellular elements in softening and extractability of sterols and ...

Profiling and Metabolism of Sterols in the Weaver Ant Genus

open access: yesNatural Product Communications, 2016
Sterols are essential to insects because they are vital for many biochemical processes, nevertheless insects cannot synthesize sterols but have to acquire them through their diet.

ABCA1-dependent sterol release: sterol molecule specificity and potential membrane domain for HDL biogenesis

open access: yesJournal of Lipid Research, 2016
Mammalian cells synthesize various sterol molecules, including the C30 sterol, lanosterol, as cholesterol precursors in the endoplasmic reticulum. The build-up of precursor sterols, including lanosterol, displays cellular toxicity.

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.

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.
