Chapter 24: Q39P (page 1125)

How many molecules of acetyl-CoA are obtained from the b-oxidation of one molecule of a 16-carbon saturated fatty acyl-CoA?

Short Answer

Expert verified

The eight molecules of acetyl-CoA are obtained from the 尾-oxidation of one molecule of a 16-carbon saturated fatty acyl-CoA.

Step by step solution

01

β- Oxidation

In 尾-oxidation,four enzyme-catalyzed reactions are repeated until the entire fatty acyl-CoA molecule has been converted to acetyl-CoA molecules. The enzymes that catalyze the reactions are 1. acyl-CoA dehydrogenase; 2. enoyl-CoA hydratase; 3. 3-l-hydroxyacyl-CoA dehydrogenase; and 4. 尾-ketoacyl-CoA thiolase

02

Reaction of conversion of 16-carbon saturated fatty acyl-CoA

The reaction of 尾oxidation is completed in four steps, and in each step, two carbon atoms are reduced. Finally, eight carbon are reduced, and eight carbon remains.
