`color(red)(Introducer)=` Sc. Robertson

According to him, the cell membrane is made of a three layer sequence of protein-lipid-protein.

The external layer is a hydrophilic layer made of protein molecules of diameter `20A-25A`. The middle layer is a light hydrophobic layer made of phospholipids of diameter `25A-35A`.

The total breadth of the cell membrane is `65A-85A`.
