Sarin action
Sarin eller isopropylmetylfluorfosfonat är en lättflyktig nervgas. Sarin upptäcktes 1938 i Tyskland, och namngavs efter de tyska upptäckarna Schrader, Ambros, Rüdiger och van der Linde. Flyktigheten, att sarin lätt förångas, gör att den kan användas i strid på ett område som senare ska ockuperas av egna soldater, eftersom gasen snabbt dunstar bort efter insats. Sarin är den mest lättflyktiga av de vanligen förekommande nervgaserna.

Webb1 okt. 2004 · Nerve agents used in chemical warfare such as tabun, sarin, VX, and soman are anticholinesterases of high potency. They produce virtually irreversible inactivation of acetylcholinesterase by alkylphosphorylation. The nerve agents also have direct action on the nicotinic, cardiac muscarinic, and glutamate NMDA receptors. Webb21 dec. 2015 · Sarin acts on cholinesterase by forming a covalent bond with the particular serine residue at the active site. Fluoride is the leaving group, and the resulting phosphoester is robust and biologically inactive.[12][13] Its mechanism of action resembles that of some commonly used insecticides, such as malathion.
