👉 In the context of biochemistry and molecular biology, a "venin" is a type of cell membrane protein that is involved in the transport of substances between different organelles or cells. Venins are found on the surface of eukaryotic cells, including bacteria, fungi, and some plant cells. Venins can be categorized into two main types: ionotropic and chelating. Ionotropic venins are responsible for transporting ions across cell membranes, while chelating venins are
