Step 1
Cholesterol is synthesized from acetyl-CoA through a series of enzymatic reactions. The key intermediate in this pathway is mevalonate, which is eventually converted into cholesterol. Show more…

(a) Palmitic acid, $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{14} \mathrm{CO}_{2} \mathrm{H}$ (b) Arachidic acid, $\mathrm{CH}_{3}\left(\mathrm{CH}_{2}\right)_{18} \mathrm{CO}_{2} \mathrm{H}$
How many molecules of acetyl-CoA are produced by catabolism of the following fatty acids, and how many $\beta$ oxidations are needed?
