How many more enzymes does the oxidation of a polyunsaturated fat such as linoleoyl-CoA (18:2)require than the oxidation of stearoyl-CoA (18:0)?

Question

Quizplus · Accepted Answer

The oxidation of linoleoyl-CoA (18:2) requires two additional enzymes compared to stearoyl-CoA (18:0), specifically the enzymes required for the desaturation of the two double bonds present in linoleoyl-CoA. The oxidation of stearoyl-CoA only requires the enzymes of beta-oxidation, which are also involved in the oxidation of linoleoyl-CoA after the double bond desaturation step. Thus, the difference between the two types of fatty acids is the need for additional enzymes for the desaturation step, making the correct choice C) 2.
