What type of agent is symbolized by "VX"?

VX is a highly toxic synthetic chemical compound classified as a nerve agent. Nerve agents, including VX, disrupt the normal functioning of the nervous system by inhibiting the enzyme acetylcholinesterase. This enzyme is crucial for breaking down the neurotransmitter acetylcholine, which is responsible for transmitting nerve signals. When acetylcholinesterase is inhibited, acetylcholine accumulates, leading to overstimulation of muscles, glands, and the central nervous system, resulting in severe symptoms, including paralysis and death if not treated promptly.

VX is characterized by its lethality, persistence in the environment, and can be absorbed through skin, inhalation, or ingestion. This unique modality of action and these properties distinctly define it as a nerve agent, making the identification of VX as such essential in both military and civilian contexts concerning chemical warfare and safety protocols.
