Lipid Structure in Triolein Lipid Droplets
The Journal of Physical Chemistry B, 2014Lipid droplets (LDs) are primary repositories of esterified fatty acids and sterols in animal cells. These organelles originate on the lumenal or cytoplasmic side of endoplasmic reticulum (ER) membrane and are released to the cytosol. In contrast to other intracellular organelles, LDs are composed of a mass of hydrophobic lipid esters coved by ...

Bacteria and Archaea account for the largest amount of biomass on earth and are major reservoirs of essential nutrients and energy. They have a simpler internal cell structure than eukaryotic cells, and in most cases they lack membrane-enclosed organelles. Archaea includes extremophilic prokaryotic organisms living in habitats that are unusual for most

Structure andSynthesis of Lipid A
2009Lipid A is the lipophilic partial structure of bacterial lipopolysaccharide (LPS), which is a characteristic and essential component of the cell surface architecture of Gram negative bacteria. LPS constitutes the outer leaflet of the lipid bilayer of outer membrane which covers the outermost surface of bacterial cells.

Purification of specific structured lipids by distillation: Effects on acyl migration
JAOCS, Journal of the American Oil Chemists' Society, 2001 The cause and effects of acyl migration during the purification of specific structured lipids by distillation were studied in a conventional batch deodorizer with stripping steam.

Structure of Oriented Lipid Bilayers
Nature New Biology, 1971X-ray diffraction studies show that lipid hydrocarbon chains are uniformly packed in bilayers and oriented so that their free ends are near the centre. This provides a model for biological membranes.

Role of lipids in prebiotic structures
Biosystems, 1980Abstract In this paper we briefly review recent work on the prebiotic formation of fatty acids, glycerol, glycerol phosphates, acylglycerols, phosphatidic acids and other lipids. This evidence demonstrates the probable occurrence of such amphiphilic molecules in the prebiotic environment, and their self-assembly into vesicles with bilayer membranes ...

AbstractMuch of the function of lipids, as in shortenings, confections, biological membranes, etc., depends on the structures they exhibit, i.e., their crystalline and mesomorphic states. Triglycerides may serve as a point of departure for considering the crystal state of lipids. The three principle cross‐sectional arrangements of long chains‐α, β′ and

Concepts of the Chemical Structure of Lipid A
Clinical Infectious Diseases, 1984Lipid A represents the covalently bound lipid component of lipopolysaccharides (LPS), the endotoxins and O antigens of gram-negative bacteria. Lipid A's of endotoxically active LPS consist of a beta(1'----6)-linked D-glucosamine disaccharide that carries phosphoryl groups in positions 1 and 4'.

Physical Structure and Behavior of Lipids and Lipid Enzymes
1963Publisher Summary This chapter describes the physical structure and behavior of lipids and lipid enzymes. The resolving power of the electron microscope and X-ray diffraction camera has required biologists to reconsider the physical and structural properties of lipids in the organization of a living cell.
