Explain the side effects of consuming denatured alcohol and its remedies.

(N/A) Methanol is $CH_3OH$,while ethanol is $C_2H_5OH$. Both undergo biological oxidation to form their corresponding aldehydes $(HCHO, CH_3CHO)$ and subsequently acids $(HCOOH, CH_3COOH)$.
Side Effects: Denatured alcohol is ethanol mixed with methanol. If an addict consumes denatured alcohol,methanol is first converted into methanal and then into methanoic acid. This can lead to blindness and death.
Remedies: $A$ patient suffering from the toxic effects of methanol consumption is treated by intravenous administration of dilute ethanol. The enzyme responsible for the oxidation of aldehyde $(HCHO)$ to acid is inhibited by ethanol,allowing the kidneys time to excrete methanol,thereby saving the patient.
