Ion channel

Simplified textbook-style generic ion channel depicted as a compact membrane-spanning transmembrane protein crossing a phospholipid bilayer. The protein has a symmetrical barrel-like or short cylindrical shape with a narrow central pore running vertically through the middle from top to bottom, clearly open at both ends. The outer structure is formed by smooth rounded or bundled subunits with subtle ring-like contours, and the channel may appear slightly wider at the membrane surfaces or gently hourglass-like. Rendered in blue, teal, blue-gray, purple, or green with clean scientific clipart or reusable icon styling, emphasizing a pore-forming membrane protein for selective ion passage rather than a pump.
