Question
Chapter 22, Problem 12P
Interpretation Introduction
Interpretation:
The balanced equation for the conversion of stearate to acetoacetate should be determined.
Concept introduction:
The fatty acids are degraded in a sequential manner, that is, two carbon units at the carboxyl end of the molecule are removed in each step. The process of beta-oxidation of fatty acids takes place inside the mitochondria, and it includes the oxidation of beta carbon of the fatty acids.
