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.

Acta Crystallographica Section E: Crystallographic Communications, 2019 The structure of the title compound, C32H51NO6, was determined from 62-year-old crystals at room temperature and refined with 100 K data in a monoclinic (C2) space group. This compound with a triterpenoid structure, now confirmed by this study, played an

Ergosterol reduction impairs mitochondrial DNA maintenance in S. cerevisiae [PDF]
, 2019 Sterols are essential lipids, involved in many biological processes. In Saccharomyces cerevisiae, the enzymes of the ergosterol biosynthetic pathway (Erg proteins) are localized in different cellular compartments.

Preparation and properties of a cell-free system from rat skin that catalyzes sterol biosynthesis
Journal of Lipid Research, 1966 Homogenates of epidermis from rat skin were centrifuged at 10,000 · g for 20 min. The supernatant fraction (“whole homogenate”) catalyzed the demethylation of lanosterol (C30) to yield C27-sterols. The rate of reaction was measured by the rate of release

Lanosterol Synthase in Dicotyledonous Plants [PDF]
Plant and Cell Physiology, 2006 Sterols are important as structural components of plasma membranes and precursors of steroidal hormones in both animals and plants. Plant sterols show a wide structural variety and significant structural differences from those of animals. To elucidate the origin of structural diversity in plant sterols, their biosynthesis has been extensively studied ...

Plant oxidosqualene metabolism: cycloartenol synthase-dependent sterol biosynthesis in Nicotiana benthamiana. [PDF]
PLoS ONE, 2014 The plant sterol pathway exhibits a major biosynthetic difference as compared with that of metazoans. The committed sterol precursor is the pentacyclic cycloartenol (9β,19-cyclolanost-24-en-3β-ol) and not lanosterol (lanosta-8,24-dien-3β-ol), as it was ...
