How do you convert ketones to alcohol?
Reduction to Alcohols
Aldehydes and ketones can undergo reduction process for the formation of either primary alcohol or secondary alcohol with the help of reagents, sodium borohydride (NaBH4) or lithium aluminium hydride (LiAlH4). Aldehydes and ketones can also form alcohol by the process of catalytic hydrogenation.What enzyme converts ketones to alcohol?
Alcohol dehydrogenases (EC 1.1. 1.1) are enzymes that catalyze the reduction of aldehydes and ketones to primary and secondary alcohols, respectively.What is the hydrogenation of ketones to alcohol?
The Hydrogenation of Ketones
A ketone is an organic compound that contains a carbonyl group (carbon-oxygen double bond) bonded to two other alkyl groups. When a ketone is hydrogenated, a molecule of hydrogen is added across the carbon-oxygen double bond to ultimately form an alcohol as the final product.- You may recall that conversion of an aldehyde or ketone to an alcohol is referred to as a reduction. The hydride from an NADH molecule or a BH4- anion acts as a nucleophile, adding H- to the carbonyl carbon. A proton source can then protonate the oxygen of the resulting alkoxide ion, forming an alcohol.
