Question

Ethylene glycol (HO - CH2 - CH2-OH) is a major component of antifreeze. In the body, it is first converted to HOOC - CHO (oxoethanoic acid) and then to HOOC – COOH (oxalic acid), which is toxic. Part A What class of enzyme catalyzes both of the reactions of ethylene glycol? Submit Previous Answers Request Answer X Incorrect; Try Again; 5 attempts remaining Part B The treatment for the ingestion of ethylene glycol is an intravenous solution of ethanol. How might this help prevent toxic levels of oxalic acid in the body? Essay answers are limited to about 500 words (3800 characters maximum, including spaces). 3800 Character(s) remaining

Answer 1

Answer: 1. Page No oo Given, Ethylene glycol CHO-CH₂ - CH₂-OH) is a Hajós component of antifreeze. In the body it is bt converted to HOOC-CHO oxoethanoic acid and then to HOOL - Cook (oxalic acid) (a) ox dekanoic acid and oxalic acid are produce on oxidation of Ethylene glycol. so these reactions are catalyzed by oxidase enzyme which belongs to class oxidoreductase. (6) Ethanol (CH₃-CH₂-OH) has the stoucture similar to ethylene glycol (HO-CH2-CH2-OH). So ethanol acts as a competitive inhibitor for ethylene glycol and reduces the production of toxic levels of oxalic acid in the body.
