                                Casein, the dominant protein in milk, is famous for its slow digestion and creamy texture, but a lesser-known fact is its powerful adhesive quality. This stickiness, which can make protein shakes difficult to clean, is a direct result of the protein's unique molecular structure and behavior when interacting with water and other substances.
