Why does the OH group add to the β-carbon rather than to the α-carbon in the second reaction in the β-oxidation of fats?

Short Answer

Expert verified

Beta oxidation occurs because the carbonyl carbon is partially positive and hence attracts -OHgroup.

Step by step solution

01

Step-by-Step SolutionStep 1: β-oxidation in fatty acids

β -oxidation in fatty acids is a process in which fatty acids are broken down to produce energy.

β-oxidation is a catabolic process where fatty acids are broken down to produce acetyl CoA. In beta-oxidation bond is broken between beta carbon and gamma carbon.

β-oxidation of fats

After observing the resonance structures as shown below it is seen that on the right-hand side structureβ carbon ofα,β unsaturated carbonyl compound has a positive charge. The nucleophilic -OHgroup, therefore, is attracted to theβ carbon.
