The 'double lives' of membrane lipids. Workshop: Anno 2000. A lipid milestone.

چکیده
The year 2000 marks the 75th anniversary of the existence of the bilayer model of biological membranes as originally proposed by Gorter and Grendel (1925). It also marks a period of excitement in understanding membrane lipids. Many lipids appear to lead double lives, serving both as membrane building blocks and as modulators of important cellular processes. Membrane lipid behavior is becoming understood at molecular and even atomic levels, through the application of sophisticated biophysical and computational approaches. The molecular causes of membrane lipid-based diseases are being established, and new technologies whereby membranes and their components can be manipulated are now being used in medical and industrial applications. These topics were discussed at ‘Anno 2000. A lipid milestone’, and the highlights of this discussion are summarized below. Physical properties of lipids ‘shape’ biomembranes

The changes in lipid composition of Pythium irregulare LX oomycetes at a stressful situation created with crude oil
Pythium irregulare oomycetes adapts with environmental changes including crude oil concentration by changing the composition of lipids in the cytoplasmic membrane and providing the required characteristics for adaptation in improper and stressful environmental situations. It was found that cultivation of Pythium irregulare LX oomycetes in the nutrient media with different concentrations of crud...
متن کاملMolecular Insight into the Mutual Interactions of Two Transmembrane Domains of Human Glycine Receptor (TM23-GlyR), with the Lipid Bilayers
Appearing as a computational microscope, MD simulation can ‘zoom in’ to atomic resolution to assess detailed interactions of a membrane protein with its surrounding lipids, which play important roles in the stability and function of such proteins. This study has employed the molecular dynamics (MD) simulations, to determine the effect of added DMPC or DMTAP molecules on the structure of D...
متن کاملAll fatty acids are not equal: discrimination in plant membrane lipids.
Plant membrane lipids are primarily composed of 16-carbon and 18-carbon fatty acids containing up to three double bonds. By contrast, the seed oils of many plant species contain fatty acids with significantly different structures. These unusual fatty acids sometimes accumulate to >90% of the total fatty acid content in the seed triacylglycerols, but are generally excluded from the membrane lipi...
متن کاملPhysical properties and functional roles of lipids in membranes
Biological membranes contain an astonishing variety of lipids. As detailed throughout this book, generation of this diversity requires elaborate metabolic pathways. The lipid compounds representing the end products of these pathways must bestow significant evolutionary advantages to the cellular or multicellular systems in which they reside, implying particular functional roles for each compone...
متن کاملLipids in leaves: fatty acid β-oxidation affects lipid homeostasis.
DNA, RNA, and proteins get a lot of attention, but without lipids, a cell is just a soup. Cellular membranes have a remarkable variety of lipids, and different organelles have different lipid compositions that must be maintained despite changes caused by vesicular trafficking among organelles (reviewed in Holthuis and Menon, 2014). Lipids move via vesicular trafficking, direct membrane contact ...
