Integral Membrane Proteins

These are <a href="Proteins">proteins</a> directly linked to the <a href="Plasma membrane">plasma membrane</a> of <a href="Cells">cells</a>; they do not have intermediate <a href="Molecules">molecules</a> between them and the <a href="Plasma membranes">plasma membranes</a>. They are also considered as proteins that fully pass through the membrane (<a href="Carrier protein">carrier proteins</a> and <a href="Channel protein">channel proteins</a>).

Peripheral Membrane Proteins

These proteins are connected to the plasma membrane through intermediate molecules (even integral proteins) by noncovalent interactions or proteins attached to only one side of the membrane; do not pass through the membrane [1].
