How are cells able to transport large molecules? How do lipid soluble molecules cross the cell membrane? How do nonpolar molecules cross the cell membrane? How are cells affected by the movement of water? Descr
Answer to: What is polarity, and how do polar molecules interact with nonpolar molecules? By signing up, you'll get thousands of step-by-step...
Hsp90 is an essential molecular chaperone responsible for the folding and activation of hundreds of ‘client’ proteins, including the glucocorticoid receptor (GR). Previously, we revealed that Hsp70 and Hsp90 remodel the conformation of GR to regulate l
In the preceding figure, we can see what happens when we place carbon tetrachloride into water. Because carbon tetrachloride is a nonpolar molecule, the interactions between adjacent molecules are very weak. As a result, we might expect carbon tetrachloride to be very soluble in water. However, ...
It’s known that there are two types of polymerases: distributive (they can make phosphodiesther bond between two nucleotides but can’t move along a template; many molecules of such a polymerase are needed to copy a template) and processive (they bind with a template, move on it and ...
The London interaction is in general the most dominant VdW force, even in molecules with a permanent dipole [42,43]. The Van-der-Waals interaction between single atoms and molecules is rather weak and short-ranged. Their potential decreases with the sixth power over the distance. In particles...
All of these molecules require GPI to be expressed at the cell surface and to function. Unlike conventional hydrophobic transmembrane protein domains that span the membrane bilayer, GPI anchors penetrate only into a single membrane leaflet. This feature, as well as the saturated fatty acyl chains ...
crystal structure (Protein Data Bank (PDB) ID:4LAV) (ref.46) and adopting different interfaces with GR (Supplementary Movies3and4). In the consensus 3D refinement map, the proline-rich loop adopts a position similar to the crystal structure, and FKBP52A116,S118,P119interact with GRHelix...
Alkanes are not soluble in water, which ishighly polar. The two substances do not meet the criterion of solubility, namely, that “like dissolves like.” Water molecules are too strongly attracted to one another by hydrogen bonds to allow nonpolar alkanes to slip between them and dissolve....
The electron cloud is largest around the hydrogen in LiH, because that hydrogen has more electrons around it than do the hydrogens in the other molecules. c. Because the hydrogen of HF is blue, we know that this compound has the most positively charged hydrogen and, the...
