Web3 jan. 2024 · Transmembrane proteins can in fact cross a membrane more than once, which also determines the location of its N- and C-termini. N-terminal end of a plasma membrane polypeptide always ends up exposed to the outside of the cell. The alpha helical domains that anchor proteins in membranes are mostly non-polar and hydrophobic themselves. Web23 dec. 2024 · Similarly, weakly hydrated anions can solubilize a hydrophobic polymer in water by accumulating in its hydration shell and reducing the aversion between the polymer and water. Conversely, anions ...
