Which one of the following coenzymes is not a part of the β-oxidation pathway?

Lauric acid, a saturated fatty acid, [12:0], is found in coconut oil.

e. How many cycles of β oxidation occur?

Capric acid is a saturated fatty acid, [10:0].

a. Draw fatty acyl capric acid activated for β oxidation.

Lauric acid, a saturated fatty acid, [12:0], is found in coconut oil.

a. Draw fatty acyl lauric acid activated for β oxidation.

The glycerol derived from lipolysis of triacylglycerols is converted into glyceraldehyde 3-phosphate, which then enters into step 6 of the glycolysis pathway. What further transformations are necessary to convert glyceraldehyde 3-phosphate into pyruvate?

How many total FADH₂, NADH, and acetyl CoA molecules will be produced when stearic acid undergoes β‑oxidation?

Tripalmitin is a TAG formed by the esterification of glycerol with three palmitic acid molecules. How many acetyl CoA molecules will be produced by the complete oxidation of tripalmitin? (Hint: consider glycerol metabolism too).

How many molecules of acetyl-CoA are produced by catabolism of the following fatty acids, and how many β oxidations are needed?

a. Palmitic acid, CH₃(CH₂)₁₄COOH

Look back at the reactions of the citric acid cycle (Figure 21.8) and identify the three reactions in that cycle that are similar to the first three reactions of the β oxidation of a fatty acid.
