Gprotein-coupled receptors are transmembrane receptors involved in cell signaling. the amino acid sequence of these proteins reveals that the polypeptide chain of the protein has seven hydrophobic regions. based on this information, what can you conclude about how the protein is associated with the cell membrane?

The polypeptide chain is likely to span the membrane seven times.

Explanation:

G-protein coupled receptor are trans membrane structure which means the the structure is present inside the cell as well as outside the cell membrane.

The amino acid sequence of the proteins reveals that the polypeptide chain has 7 hydrophobic regions so it is obvious that it will be having seven hydrophillic end.

This states that the polypeptide chain is spanning the cell membrane seven times.

im not in connections yet but i might can you some questions. what grade are you in?

there are so many examples for that in different areas, like biology experiment carried out in our lab recently.

here's one link:
