membraanista

Membraanista is a Finnish-language term that translates to "membrane" in English. In a biological context, a cell membrane is a selectively permeable barrier that encloses the cytoplasm of a cell. It is primarily composed of a phospholipid bilayer with embedded proteins, which regulate the passage of substances into and out of the cell. This vital structure plays a crucial role in maintaining cellular homeostasis, communication, and transport.

Beyond biology, the term "membraanista" can refer to artificial membranes used in various industrial and technological applications. These can include filtration membranes for water purification, dialysis membranes for medical treatments, or gas separation membranes in chemical processes. The properties of these artificial membranes, such as pore size, permeability, and chemical resistance, are tailored to their specific function. The concept of a membrane as a barrier or interface is central to its meaning, whether in living organisms or engineered systems.
