A Role for a Sterol and a Sterol Precursor in the Bacterium Rhodopseudomonas palustris [PDF]

Journal of General Microbiology, 1964
SUMMARY: The multiplication of the purple photosynthetic bacterium Rhodopseudomonas palustris is inhibited by the hypocholesteraemic agents benzmalecene and triparanol. This inhibition is annulled by oleic acid, ergosterol, squalene, farnesol and lanosterol, in that order, but not by mevalonic acid, geranyl acetate, palmitic or stearic acids.

Beyond Gut Modulation: A Critical Review of the Therapeutic Potential, Safety, and Clinical Prospects of Natural Polysaccharides for IBD

Food Safety and Health, EarlyView.
In this review, we critically summarized the application of natural polysaccharides (NPs) for the treatment of IBD. This approach combines, in a unique way (right), the basic structure–activity relationships of NPs from different origins (left) with their multipronged mode of action, which involves modulation of the gut microbiota and other ...

Sterol biosensor reveals LAM-family Ltc1-dependent sterol flow to endosomes upon Arp2/3 inhibition

, 2020
Sterols are crucial components of biological membranes, which are synthetized in the ER and accumulate in the plasma membrane (PM). Here, by applying a genetically encoded sterol biosensor (D4H), we visualize a sterol flow between PM and endosomes in the

Chemistry Underlying the Behavior of Food and Agricultural Components During Industrial Manufacturing Processes and Its Implications in Quality Assurance, Food Quality, and Food Safety Management: A Systematic Review

Food Safety and Health, EarlyView.
Industrial manufacturing processes have transformative effects on the components of food matrix. These transformations in food matrix and components have direct implications for quality assurance (QA), food quality (e.g., nutritional profile and texture), and food safety management (e.g., pathogen control and toxin mitigation). ABSTRACT This systematic

Sterol-modified plants reduce aphid performance by limiting sterol availability

Sterols are essential for eukaryotic cell structure and metabolism, yet insects cannot synthesize them de novo and must acquire them through their diet.

A sterol biosynthetic pathway in Mycobacterium

, 1998
The genome sequence of Mycobacterium tuberculosis (and also M. leprae) revealed a significant number of homologies to Saccharomyces cerevisiae sterol biosynthetic enzymes. We addressed the hypothesis of a potential sterol biosynthetic pathway existing in
