Ionophores

Ionophores are compounds that transport ions across membranes, categorized into carrier and channel forming types. They alter membrane permeability and can exhibit cytotoxic properties, with applications in cell physiology, biotechnology, and medical treatments like antifungal and antibacterial activities. Notable examples include valinomycin, which selectively transports potassium, and gramicidin A, which facilitates sodium and potassium passage.
