Comments A characteristic of the interiors of all cells is the high total concentration of macromolecules they contain. Such media are termed ‘crowded’ rather than ‘concentrated’ because, in general, no single macromolecular species occurs at high concentration but, taken together, the macromolecules occupy a significant fraction (typically 20–30%) of the total volume.
