Is Integral protein the same with transmembrane protein?
If not,please tell me the difference..
thanks

Transmembrane proteins are proteins that span both halves of a lipid bilayer of a membrane and just refer to the orientation/location of the protein in a cell membrane.
Most integral membrane proteins are transmembrane but not all transmembrane proteins are integral membrane proteins.
1. There are three types of integral membrane proteins a. transmembrane, b. membrane associated and c. lipid-linked.
2. Integral membrane proteins are a lot harder to remove from the cell membrane. They are attached to the cytoskeleton of a cell and therefore do not diffuse ("flow") with the cell membrane because of the anchoring.

trans-membrane proteins usually cross the membrane and some of its pars will be inside and outside of the membrane it usually has a alpha helical structure with hydrophobic amino acids integral membrane protein usually embedded in the membrane and it makes the membrane more Mosaic than fluid

I believe they are the same.
