yes, transmembrane proteins have both polar and non-polar regions. This is because these proteins are dispersed through the membrane almost like pieces of stones. So, to be inside the hydrophobic region of the phospholipid bi-layer AND also outside of it in the water or aqueous solution they transmembrane protein needs to be amphipathic.

∙ 12y agoNO, cause peripheral proteins located outside which either stick to integral proteins or hydrophilic heads of phospholipid molecules. Thus, peripheral proteins are hydrophilic. Additional information: both integral proteins and lipid-anchored proteins are amphipathic molecules since they possess both hydrophobic and hydrophilic characteristics.
Hope my information helps you.

What type of proteins don't go through the bilayer?
It important that some proteins extend all the way through the bilayer of a plasma membrane. This is to offer protection to the cell and also facilitate the transport of various substances in and out of the cell.
What are facts about integral membrane proteins?
They are usually transmembrane proteins.
What are channels in the pumps in the cell membrane mad of?
These are proteins. Transmembrane proteins span the entire membrane.
What are integral and transmembrane proteins?
the proteins that protrude from both surfaces of the bilayer
What component of a phospholipid membrane helps the cell interact with its polar watery environment?
Membrane proteins.

Membrane proteins.
Are integrins embedded in the lipid bilayer?
Yes they are, as well as glycoproteins, integral proteins, and transmembrane proteins. Peripheral proteins however are not embedded in the lipid bilayer.
What is an anoctamin?
An anoctamin is any of a group of transmembrane proteins associated with the channelling of chloride ions.
Cellular adhesion molecules are?
Cell adhesion molecules are groups of transmembrane proteins that mediate.
What are the channels in the cell membrane made of?
Most channels are made of specialized transmembrane proteins.
What is a cadherin?
A cadherin is any of a class of transmembrane proteins important in maintaining tissue structure.
What is another name for integration?
Another name for integral proteins is integral membrane proteins.Most are transmembrane proteins, which span the entire depth of the membrane.
