Abstract:
The results shown in this paper indicate that the permeability properties of egg yolk phosphatidylcholine sonicated vesicles as detected by the leakage of carboxy fluorescein changes according to the Ca2+ content. Vesicles containing Ca2+ show a higher rate of leakage than those containing Na+ solutions in response to the increase of Ca2+ concentration in the outer solution. The results are interpreted in terms of the rigidity promoted by Ca2+ and are compared to those obtained with long and short chain alcohols.

Overview of Fatty Acid Metabolism
Fatty acids are catabolized in a process called beta-oxidation, which takes place in the matrix of the mitochondria and converts their fatty acid chains into two-carbon units of acetyl groups. The acetyl...

Flippase
Eukaryotic flippases are type-IV P-type ATPases or P4-ATPases belonging to P-type ATPase family proteins that are membrane-bound pumps involved in the ATP-mediated transport of ions and molecules across the membrane. Flippases flip specific phospholipids from the outer to the inner leaflet of a membrane. All P4-ATPases have one...
