A sequence of amino acids with a relatively high hydropathy is very likely to function by
A)being at the active site of an enzyme.
B)being embedded in a cell membrane.
C)making a protein soluble.
D)being on the protein surface.

Question

Quizplus · Accepted Answer

Amino acids with high hydropathy are typically hydrophobic, meaning they repel water. Amino acids with high hydropathy are more likely to be found embedded in cell membranes, where they can interact with the hydrophobic parts of the membrane. They would not likely be found at the active site of an enzyme or on the protein surface as they would be more likely to be buried in the interior of the protein. Making a protein soluble would require amino acids with low hydropathy, as these amino acids are more likely to interact with water.
