As observed for PA, the SA values for membrane proteins are substantially lower as well (Table 2), indicating that, in general, predicting the SCL is more difficult for membrane proteins than for soluble proteins.
This difference makes getting into cells more difficult: Whereas membrane-clad viruses can fuse their membrane with the cell, much like two soap bubbles merging, SV40 needs to find another way inside.
It is even more surprising because the lipophilicity of these products makes their transport across membranes more difficult [ 19, 20].
Miniature cells suffered from higher than expected interfacial resistance which increased with time and this may be due either to more difficult hydration control in the membrane at smaller dimensions, or less compression in the smaller scale size leading to higher flow field/diffusion layer interfacial resistances.
In healthy controls, the synovial membrane was more difficult to identify.
Second, aa-NMPs would be more difficult to diffuse through the membrane, thus also contributing to the retention of amino acids.
He argues the transition from a Gram-positive membrane structure to a Gram-negative membrane would be much more difficult than the other direction, so this excludes the root from the single membrane prokaryotes.
In contrast to artificial membranes consisting of a defined multi-component system, data obtained with biological membranes are more difficult to explain and need to be interpreted with caution.
While structural determination has progressed in recent years, most membrane protein crystal structures solved are taken from bacteria because eukaryotic membrane proteins are more difficult to crystallize [ 36].
The result from "extended Derjaguin, Landau, Verwey, Overbeek" (XDLVO) calculation indicates that with the increase of shear rate, it is more difficult for algae to foul the membrane.
