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.

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.

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

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.

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 ...

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

open access: yeseLife, 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.

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.

Evolution of Extra Virgin Olive Oil Quality under Different Storage Conditions

open access: yesFoods, 2021
The extent and conditions of storage may affect the stability and quality of extra virgin olive oil (EVOO). This study aimed at evaluating the effects of different storage conditions (ambient, 4 °C and −18 °C temperatures, and argon headspace) on three ...

Sterols in the small intestine of the rat, guinea pig, and rabbit

open access: yesJournal of Lipid Research, 1971
The sterol content and composition of the small intestinal mucosa has been studied in the rat, guinea pig, and rabbit. In the three species, noncholesterol sterols formed a large proportion of the total sterol content. In the rat, the contribution due to
