Soman (or GD, EA 1210, Zoman, PFMP, A-255, systematic name: O-pinacolyl methylphosphonofluoridate) [1] is an extremely toxic chemical substance. It is a nerve agent , interfering with normal functioning of the mammalian nervous system by inhibiting the enzyme cholinesterase .
The blood of people killed by blood agents is bright red, because the agents inhibit the use of the oxygen in it by the body's cells. [2] Cyanide poisoning can be detected by the presence of thiocyanate or cyanide in the blood, a smell of bitter almonds, or respiratory tract inflammations and congestions in the case of cyanogen chloride ...
A chemical weapon agent (CWA), or chemical warfare agent, is a chemical substance whose toxic properties are meant to kill, injure or incapacitate human beings.About 70 different chemicals have been used or stockpiled as chemical weapon agents during the 20th century, although the Organisation for the Prohibition of Chemical Weapons (OPCW) has an online database listing 35,942 chemicals which ...
Stereoisomers of Soman, a G-series nerve agent and suicide inhibitor of acetylcholinesterase.Note the non-carbon chiral center.. In biochemistry, suicide inhibition, also known as suicide inactivation or mechanism-based inhibition, is an irreversible form of enzyme inhibition that occurs when an enzyme binds a substrate analog and forms an irreversible complex with it through a covalent bond ...
The most widely used portable testing device is the Test-mate ChE field test, [30] [31]: 13 which can be used to determine levels of Red Blood Cells (RBC), AChE and plasma (pseudo) cholinesterase (PChE) in the blood in about four minutes. This test has been shown to be just as effective as a regular laboratory test and because of this, the ...
An Astrocyte, a cell notable for maintaining the blood brain barrier. Ammonia toxicity is often seen through two routes of administration, either through consumption or through endogenous ailments such as liver failure. [89] [90] One notable case in which ammonia toxicity is common is in response to cirrhosis of the liver which results in ...
Chlorosoman is a chlorine analog of soman. It is a highly toxic organophosphorus compound and used as the precursor substance for soman nerve agent. [2] Its physical properties are estimated. Soman is insoluble in water, with a boiling point of 223 degrees Celsius and a melting point of -27 degrees Celsius.
Attracted cells move through the gradient towards the higher concentration of chemokine. The major role of chemokines is to act as a chemoattractant to guide the migration of cells. Cells that are attracted by chemokines follow a signal of increasing chemokine concentration towards the source of the chemokine.
