Unsaturated

... membranes act the same way in point of permeability (prokaryotic vs. eukaryotic; membranes rich in saturated fatty acid chains vs. rich in unsaturated ones; etc.)? In other words, is there any difference in the fine structure among membranes that could affect permeability (aside from having ...

... specific for only water molecules. Of course, water can move through membrane directly. It is because of special membrane structure (saturated and unsaturated fat acids, cholesterol) and conditions under which are the membrane (for example temperature). First question is pretty difficult. I think ...

... feed electrons into the electron transport pathway which also produces ATP and reoxidizes NADH back into NAD+ for re-use. Arachidonic acid is an unsaturated twenty-carbon fatty acid precursor to a number of molecules like the prostaglandins, thromboxanes, prostacyclins and leukotrienes. The whole ...

... the carbon atoms. If there are only double bonds then the fatty acid chain is saturated. If there are double bonds then the fatty acid chain is unsaturated.

... be water within the chains. But then I read that the phospholipid bilayer is fluid. Why? Im not sure but is it because of the kinks formed by the unsaturated fatty acid tails, they cause a break in the close alignment of the hydrophobic interior, does this allow a small amount of water in? Does ...
