Membraanilla

Membraanilla is a term that can refer to several things, primarily in the context of biology and materials science. In a biological sense, a membraanilla refers to a cell membrane, which is a selectively permeable boundary that encloses the cytoplasm of a cell. This membrane is composed of a lipid bilayer with embedded proteins and plays a crucial role in regulating the passage of substances into and out of the cell. It is vital for maintaining cellular integrity and function, participating in processes like nutrient uptake, waste removal, and cell signaling.

Beyond the cellular level, the term can also be applied to other types of membranes. For instance, in the study of materials, a membraanilla might describe a thin, porous sheet used in filtration or separation processes. These artificial membranes are engineered with specific pore sizes and chemical properties to selectively allow certain molecules or particles to pass through while retaining others. Applications range from water purification and gas separation to drug delivery systems. The specific context in which "membraanilla" is used will determine its precise meaning, but it generally denotes a thin barrier that controls the movement of substances.
