ethylene glycol structure

Ethylene Glycol

Ethylene Glycol Ethylene glycol is a diol an alcohol with a molecular structure that contains two hydroxyl (OH) groups and terephthalic acid is a dicarboxylic aromatic acid an acid with a molecular structure that contains a large six-sided carbon (or aromatic) ring and two carboxyl (CO2H) groups

ETHYLENE GLYCOL (PIM 227)

Ethylene glycol undergoes enzymatic metabolism principally in the liver and kidneys It is the accumulation of the acidic metabolites produced by this process that are responsible for toxicity The initial step in metabolism is the conversion of ethylene glycol to glycoaldehyde mediated by alcohol dehydrogenase
