Annotating the mevalonate pathway and usage in 3 articles

[edit]

@Boghog: This diagram currently suggests that mevalonate is metabolized directly into cholesterol, which it isn't; do you think it would help to clarify this if I added a "mevalonate pathway" annotation next to the line connecting mevalonate to cholesterol? If I were to add that annotation, I could use either an unpiped link to the article on the mevalonate pathway or a piped link to File:Mevalonate pathway.svg, which I think would be a better link target than the article for this purpose.

Also, β-hydroxybutyrate, acetoacetate, and β-hydroxybutyrate dehydrogenase all lack a metabolic pathway diagram at the moment. I realize that HMG-CoA (KEGG link) and acetoacetate (KEGG link) are generated through several metabolic pathways – not just from leucine – so I could indicate this in the caption if this diagram is transcluded to those articles. Alternatively, I could crop out everything above HMG-CoA or HMB-CoA in this diagram and add that to those articles instead. Besides this template, the only other high-quality image I've seen which illustrates those 3 articles I mentioned in a metabolic pathway is File:Ketogenesis.svg. Which of these diagrams do you think is better suited for those articles? Seppi333 (Insert ) 07:36, 31 January 2018 (UTC)[reply]

Nevermind, I went ahead and added the mevalonate pathway image file annotation and annotated the thiolase enzyme for acetyl-CoA↔acetoacetyl-CoA. Seppi333 (Insert ) 15:17, 1 February 2018 (UTC)[reply]
