Phospholipid in Biological News

Dominant cholesterol-metabolism ideas challenged by new research

... enzyme plays a major role in the transfer of a phospholipid called phosphatidylserine (PS) from the inside ... membrane of normal cells showed that the rate of phospholipid transport into the cell is not affected by the ... ABC1 in apoptosis. Did ABCA1 cause or activate phospholipid transport across the cell membrane only during ...

Too hot to handle! Scientists identify heat sensing regulator

... that Pirt interacts with yet another molecule in the cell, a so-called acidic phospholipid, allowing access to TRPV1. According to Dong, through this phospholipid Pirt somehow changes the TRP channel, perhaps by opening it wider, or maybe by causing it to stay open longer. And the result is elevated pain ...

Biophysical Society announces winners of 2008 Student Travel Awards

... of Colorado, Boulder, Stepping of Individual RecBCD Molecules. Thomas Chadwick, North Carolina State University, Molecular Mechanism of phospholipid Transfer by Lipid Transporter Protein Sec14p. Hao Chen, Purdue University, Predicting the Error of Template-Based Protein Structure Modeling ...

New clinical data shows chromium picolinate improves cognitive function

... an essential trace mineral that promotes healthy blood sugar, which is important because glucose helps fuel the brain. PS is a naturally occurring phospholipid nutrient essential to the functioning of all cells of the body, but is most concentrated in the brain. PS supports communication between brain cells ...

Solution to bacterial mystery promises new drugs

... Therefore, the way gram-positive bacteria make phospholipid building blocks remained a mystery for over more ... two enzymes, called PlsX and PlsY, to kick off phospholipid synthesis. "In fact, the biochemical pathway ... fatty acid to G3P. These steps initiate membrane phospholipid formation required for cell growth. "Our ...

Liposome finding implies electrical effect on cell development

... liposomes ?cell-like "water balloons" composed of artificially created phospholipid bilayers similar to natural cell membranes ?have revealed unexpected ... microtubules were observed to immediately form and extend from the phospholipid balloon, like a seed putting forth a stalk or root. Hayes believes that ...

Bugs expose underground carbon traffic system 10 times more important than fossil fuel burning

... transporting carbon from plants to soil. As a final check the researchers examined both the cores with and without Collembola for a particular phospholipid fatty acid (PLFA) that is characteristic for AM mycelia. They found that this particular PLFA contained significant amounts of 13C in cores not ...

Beyond genes: Lipid helps cell wall protein fold into proper shape

... looked at how a protein called GabP, which transports an amino acid across the membrane of the bacterium E. coli, is affected by the presence of a phospholipid named phosphatidylethanolamine, or PE for short. Phospholipids, unlike their fatty acid and cholesterol cousins, include a phosphate group that ...

Self-assembled nano-sized probes allow Penn researchers to see tumors through flesh and skin

... Discher in the mid-1990s, function much like the bilayered membranes of living cells. Whereas cell membranes are created from a double layer of fatty phospholipid chains, a polymersome is comprised of two layers of synthetic co-polymers. Like a living cell, the polymersome membrane has a hydrophobic core. The ...
