Sentences with phrase «phospholipid molecules»

Lecithin is an emulsifier (used to keep fats / oils dispersed and in suspension): phospholipid molecules (such as lecithin) contain hydrophobic and hydrophilic elements; the hydrophobic portion has an affinity for fats and oils, and the hydrophilic portion has an affinity for water.

Not exact matches

For years materials scientists have tried reconstructing cell membranes following nature's recipe, which calls for fat - based molecules called phospholipids as the main ingredient.

In this publication, under the title of «Membrane - Derived Phospholipids Control Synaptic Neurotransmission and Plasticity», the Cadiz scientists have reflected the work of years that has led them to identify a molecule, Lysophosphatidic acid (LPA), as a possible element implicated in the link between the metabolic state of an organism and its cerebral function.

Most surfactants, like soap molecules in bubbles and phospholipids in cellular membranes, have small water - loving (hydrophilic) heads and long fat - loving (hydrophobic) tails that determine how they arrange in space.

Ganglioside Influence on Phospholipid Films Investigated With Single Molecule Fluorescence Measurements.

Researchers theorized the presence of an «azotosome» — a cell membrane made of nitrogen, carbon and hydrogen molecules — as opposed to the phospholipid membrane found on terrestrial cells.

Daptomycin - resistant Enterococcus faecalis diverts the antibiotic molecule from the division septum and remodels cell membrane phospholipids.

Certain particle compounds may directly generate ROS in vivo because of their surface chemistry (eg, metals, organic compounds, and semiquinones) or after bioactivation by cytochrome P450 systems (eg, polycyclic aromatic hydrocarbon conversion to quinones).6, 290 a, 290 b A particle surface or anions present on otherwise more inert particles may disrupt iron homeostasis in the lung and thereby also generate ROS via Fenton reactions.291 Other PM constituents may do so indirectly by the upregulation of endogenous cellular sources (eg, nicotinamide adenine dinucleotide phosphate [NADPH]-RRB- oxidase) 292,293 or by perturbing organelle function (eg, mitochondria) by taken - up PM components.261 Particle stimulation of irritant and afferent ANS fibers may also play a role in local and systemic oxidative stress formation.294 Given the rich antioxidant defenses in the lung fluid, secondarily generated oxidization products of endogenous molecules (eg, oxidized phospholipids, proteins) or a reduction in endogenous antioxidants per se may be responsible at least in part for the state of oxidative stress in the lungs (along with instigating the subsequent cellular responses) rather than ROS derived directly from PM and its constituents.

Every cell in the body has a cell wall made of phospholipids — a combination of different fats and molecules that need to let specific nutrients in the cell and waste and toxins out.

A recent in vitro study showed that incorporating a greater extent (2-fold) of TFA in the phospholipid fraction of endothelial cells significantly increased the expression of endothelial adhesion molecules, including ICAM - 1 (25).

The really crucial molecules are the phospholipids, especially phosphatidylcholine.

From a physiological and biochemical perspective, the cell membrane consists of a «phospholipid bilayer» — two rows of molecules composed primarily of fats (lipids) and phosphorus (in a special form called «phosphate» that involves a combination of phosphorus with oxygen and hydrogen).
