The body actually produces formaldehyde naturally, but enzymes in the body break it down — first into formate (formic acid) and then into carbon dioxide. Since most of the formaldehyde that we all … WebThe addition of acid to the hemiacetal creates an acetal through the following mechanism: 1. The proton produced by the dissociation of hydrochloric acid protonates the alcohol molecule in an acid‐base reaction. 2. An unshared electron pair from the hydroxyl oxygen of the hemiacetal removes a proton from the protonated alcohol. 3. dhi bath beehive
