Question
Chapter 27, Problem 60P
Interpretation Introduction
Interpretation:
To explain how many turns of the spiral are there in the ß−oxidation of (a) lauric acid and (b) palmitic acid.
Concept introduction:
As a general principle, the number of fatty acid spiral turns is always one less than the number of acetyl CoA groups formed.

Does the oxidation number change for the carbon atom to which the phosphate is attached? (i.e.,
does C3 in 3PG have a different oxidation number than C2 in 2PG?) If so, does it become higher
or lower?
Oxidation number decreases when the phosphate is moved from C3 to C2. Carbon 3 has an oxidation
number of 0; carbon 2 has an ox. number of +1.
There is no change in the oxidation number, both atoms have oxidation number of -1.
Oxidation number increases when the phosphate is moved from C3 to C2. Carbon 3 has an oxidation
number of 0; carbon 2 has an ox. number of +1.
Oxidation number decreases when the phosphate is moved from C3 to C2. Carbon 3 has an oxidation
