WebMetabolites of ethylene glycol produce severe metabolic acidosis and damage to the brain, heart, and kidneys. Severe poisoning is potentially fatal if treatment is inadequate or delayed. Acute Exposure. Ethylene glycol is a dehydrating agent and is mildly irritating to the skin and mucous membranes after prolonged contact. WebHowever, bioconversion experiments revealed metabolism of ethylene glycol by both strains, with the temporal accumulation of glycolic acid and glyoxylic acid for strain KT2440. This accumulation was further increased by targeted mutagenesis. The key enzymes and specific differences between the two strains were identified by comparative proteomics.
WebSep 26, 2024 · Ethylene glycol, the parent compound, is inebriating but generally considered nontoxic. The parent compound is osmotically active and is responsible for the increased osmolality observed in the early course of exposure prior to metabolism.
