Lipid components and oxidative status of selected specialty oils [PDF]
, 2012 Many vegetable oils are marketed as specialty oils because of their retained flavors, tastes and distinct characteristics. Specialty oil samples which were commercially produced and retailed were purchased from local superstores in Reading, UK ...

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 ...

Sterols in Red and Green Algae: Quantification, Phylogeny, and Relevance for the Interpretation of Geologic Steranes [PDF]
, 2008 Steroids, a class of triterpenoid lipids with high preservation potential, are widely distributed in sedimentary rocks. All eukaryotes have a physiological requirement for these molecules, making steroids important biomarkers for aiding our understanding

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.

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.

Plant sterol metabolism with emphasis on glycoalkaloid biosynthesis in potato [PDF]
, 2007 Glycoalkaloids are secondary metabolites present within species of the family Solanaceae. They are toxic to humans and animals, and it is important to keep the levels in potato (Solanum tuberosum L.) tubers below the safe limit for consumption ...

Selective sterol accumulation in ABCG5/ABCG8-deficient mice
Journal 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

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

Sterol content of the Myxomycetes Physarum polycephalum and P. flavicomum
Journal 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.
