Textbook Question
Chapter 24, Problem 2P
Tracing Carbon Atom Incorporation in Fatty Acids (Integrates with Chapters 18 and 19.) Use the relationships shown in Figure 24.1 to determine which carbons of glucose will be incorporated into palmitic acid. Consider the cases of both citrate that is immediately exported to the cytosol following its synthesis and citrate that enters the TCA cycle.

In step 2 of the fatty acid biosynthesis, the acetyl-S-synthase condenses the acetyl group (C2)
with a malonyl-ACP (C3) and subsequent decarboxylation to acetoacetyl-ACP (C4). Give the
molecule [A] after condensation and before decarboxylation in the reaction below.

During fatty acid biosynthesis, is it correct that the product detaches from fatty acid synthase complex when the chain length is 16 carbons?
4.2
The first step in amino acid catabolism usually involve transamination. Since ammonia is a
serious neurotoxin, the body maintains the nitrogen and ammonia balance carefully.
Discuss the pathway, organelle and organs involved in maintaining this balance. Provide a
schematic presentation of the pathway to supplement your discussion.
