Glycerol is a three-carbon molecule that functions as the backbone of these membrane lipids ... On the other hand, cell membranes restrict diffusion of highly charged molecules, such as ions ...

The gas exchange system is made from key parts, each of which has a different function ... in red blood cells. The exchange of these two gasses occurs by a process called diffusion.

Early experiments, often by physicists, led to the understanding that the cell membrane was lipid in nature ... that determine cell structure and function. The interior of a cell is an aqueous ...

Materials being examined currently are the electrolyte membrane, gas diffusion layer, catalyst, and ionomer. We examine material function at glucose concentrations similar to physiological levels to ...

We have developed a one-dimensional differential reactor that functions as a Stirred Tank Reactor PEM fuel cell ... diffusion time in the plenum, so the gas phase compositions are uniform, and the ...

"But having both a bilayer-forming lipid, which provides the basic structure for the cell membrane ... they continued to function surprisingly well." Arriving at this minimal lipid combination ...
