What are the constraints on the architecture of membrane-integral proteins that lead to the membrane-spanning regions of such proteins being less diverse in structure than soluble proteins?

The structure and function of cells is critically dependent on membranes, which not only separate the interior of the cell from its environment but also define the internal compartments of...

True

Pb2O3

=207.2 amu (Pb)

C) Tertiary structure

All are soluble in water. It means that a compound dissolves in water, saying in other words, they form one phase upon mixing with water. They are soluble because all...

PbI2 is more soluble in NaI, because both substance react with other substance.

The most common organic acids are carboxylic acids and phenols. Carboxylic acids are usually considered stronger acids than phenols, but both of these acids will react with NaOH (a...

Because phenyl group in benzoic acid is much less polar then methyl in acetic acid. The more substance is polar, the more its solubility.

Molar mass of Pb= 207.2g500/207.2= 2.413Mole ratio Pb:O2= 2:3Molar mass of O2= 31.998= 31.998×2.413×3/2= 115.823g
