Question
Chapter 23.3, Problem 1QC
Summary Introduction
To review:
The basic steps of β-oxidation and the fate of the resulting acetyl-CoA (coenzyme A) groups.
Introduction:
The fatty acids present in the body are composed of triacylglycerol joined by the long hydrocarbon chains. The decomposition of fatty acids takes place in the mitochondria and the peroxisomes by the process of β-oxidation.
