The lipophilic (or hydrophobic) ones are slightly more likely to hold interior positions than the hydrophilic ones.

The protein's amino acids that are within the lipid bilayer generally have lipophilic side chains. They form a helix with the side chains facing out, so the lipids within the bilayer attract and stabilize this arrangement of the protein, keeping it in the lipid bilayer
When a receptor protein acts as an enzyme, the receptor protein activates a second messenger that acts as a signal molecule within the cell. Resources: HOLT Biology Textbook - 9th grade edition Chapter 4, Cells and Their Environment.
Simply stated: ProteinsChannels within the structure of the cell membrane are composed of proteins. A protein that forms an ion channel through a membrane is called a transmembrane protein.
There are two main ways a protein can travel within the cell:Transportation inside a versicle - a vesicle is a membrane bound packet that can hold a protein in its interior and then shift it to a different location within the cellTransportation via a motor protein - motor proteins are structures that can carry a protein and walk along the cytoskeletal framework of the cell and deliver the protein to its destination.
The noun 'interior' is a concretenoun as a word for the internal space within something, a physical space.The noun 'interior' is an abstract noun as a word for a division or department responsible for the matters that take place within a state or nation.
anything within the passenger compartment of the vehicle would be considered the interior.
Interior means within, like the interior of a house. If you are doing geometry, the interior of a shape is it's inside.
A protein is driven into its structure by hydrophobic interactions with water. The final folding of a protein is determined by its primary structure-by the chemical nature of its side groups. Many proteins can be fully unfolded ("denatured") and will spontaneously refold back into their characteristic shape. The stability of a protein, once it has folded into its 3-D shape, is strongly influenced by how well its interior fits together. When two nonpolar chains in the interior are in very close proximity, they experience a form of molecular attraction called van der Waal's forces. Individually quite weak, these forces can add up to a strong attraction when many of them come into play, like the combined strength of hundreds of hooks and loops on a strip of Velcro. They are effective forces only over short distances, however; there are no "holes" or cavities in the interior of proteins. That is why there are so many different nonpolar amino acids (alanine, valine, leucine, isoleucine). Each has a different sized R group, allowing very precise fitting of nonpolar chains within the protein interior. That's why a mutation that converts one nonpolar amino acid within the protein interior (alanine) into another (leucine) very often disrupts the protein's stability; leucine is a lot bigger than alanine and disrupts the precise way the chains fit together within the protein interior. A change in even a single amino acid can have profound effects on protein shape and can result in loss or altered function of the protein.
