Fat from Tenebrionidae bugs – Sterols content, fatty acid profiles, and cardiovascular risk indexes [PDF]

, 2019
This work focused on analysing the content of selected sterols and profile of fatty acids of edible insect species – mealworm (Tenebrio molitor) and superworm (Zophobas morio), which are expected to increase their usability in human nutrition.

Heritability of plasma noncholesterol sterols and relationship to DNA sequence polymorphism in ABCG5 and ABCG8

Journal of Lipid Research, 2002
The plasma concentrations of cholesterol precursor sterols and plant sterols vary over a 5- to 10-fold range among normolipidemic individuals, and provide indices of the relative rates of cholesterol synthesis and fractional absorption.

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

Journal 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.

Esterification of injected epicoprostanol in a human subject

Journal of Lipid Research, 1969
That a necessary requirement for in vivo esterification of 3-hydroxy sterols is the equatorial conformation of the hydroxyl group has been substantiated by the administration of epicoprostanol-3β-3H (3-OH equatorial) to a man with a complete biliary ...

The effects of sterol structure upon sterol esterification [PDF]

Atherosclerosis, 2010
Cholesterol is esterified in mammals by two enzymes: LCAT (lecithin cholesterol acyltransferase) in plasma and ACAT(1) and ACAT(2) (acyl-CoA cholesterol acyltransferases) in the tissues. We hypothesized that the sterol structure may have significant effects on the outcome of esterification by these enzymes.

Sterol concentration and distribution in sunflower seeds (Helianthus annuus L.) during seed development [PDF]

, 2010
Sunflower seeds are currently used for edible oil production. Among oil minor compounds, phytosterols are of special interest due to their cholesterol reducing properties.

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

Frontiers 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 ...

Sterol content in sunflower seeds (Helianthus annuus L.) as affected by genotypes and environmental conditions [PDF]

, 2010
Phytosterols play essential roles in many plant cell mechanisms. They are of industrial interest since, as part of the diet, they can reduce Low Density Lipoprotein cholesterol.

Profiling and Metabolism of Sterols in the Weaver Ant Genus

Natural 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

Journal 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.
