Overall: 
*In the lead, we have ref 3 (Oregon State factsheet) cited in various passages, but I don't see "β-carotene 15,15'-dioxygenase", or "SCARB1", in the source. Granted, it's a very good one and definitely MEDRS-compliant, but it simply does not pinpoint to specific genes/enzymes. Copy from the main body.
- Wrong use of ref #3 (Oregon) in lede replaced by use of existing refs Wu2016 and PKINVitA2020.
- In Definition, where you mention an irreversible reaction, if you have an irreversible reaction (retinal -> retinoic acid), you can't have arrows to both sides. Either it is reversible, or the arrow should go one way.
- Fixed
- Trifarotene is a retinoid, but does not appear in ref 11. Reach to that article and cite a source from that article.
- Ref added confirming that trifarotene is a retinoid. Same ref used in medical uses, topical.
- Wikilink ester in lead and in the first occurrence of the text, also DNA, ethanol, euros, etiological (better subsitute with an easier word, like "causal" or something to that effect), British Ministry of Information.
- Have done ester, DNA and Euros. Still trying to find ethanol and etiological
- Fixed etiological (wikilink).
- Have done ester, DNA and Euros. Still trying to find ethanol and etiological
Expression of more than 500 genes are responsive to retinoic acid
-> expression (subject of the sentence) is singular, so must be "is responsive".- Fixed

all capitalised?- Not capitalized in the Research section; am I missing another location?
- Use Ctrl+F to search for it. I've fixed it for you. Szmenderowiecki (talk) 22:35, 24 March 2022 (UTC)

In 2001, the European Commission imposed total fines of 855.22 Euros on these and five other companies for their participation in eight distinct market-sharing and price-fixing cartels that dated back to 1989.
That's dubious - did the European Commission actually fine three companies for what is an average salary in Central-Eastern Europe - that would be interesting as a hook if true? (i.e. isn't it supposed to be "millions"?) Besides, "euro" is not capitalised.- Yes, millions, Euros capitalized, and reference now provided
- Euros are not capitalised, as no currency is; see relevant article, also wikilinked it for you (you seem to have glanced over it).
- Yes, millions, Euros capitalized, and reference now provided
- Per chemical convention (cis–trans isomerism), italicise all instances of cis and trans.
- Fixed
After this is remedied, I see no obvious issues to fix in the article. The article passes the formal criteria, is reasonably sourced (spot checks revealed minor problems, but not something that disqualifies the article), is neutral, free of plagiarism as far as Earwig goes, the hook is cited and fine for a DYK. Just fix these issues as mentioned, and possibly any other issues should you notice them.
- David notMD, I've helped with some issues you haven't noticed; now the only one is the lead. You aren't obliged to provide refs in lead per MOS, but when you do, please make sure that we can verify info from the source as provided in the text. After you make the decision, I'm totally fine with promoting the article, good job. Szmenderowiecki (talk) 22:35, 24 March 2022 (UTC) Szmenderowiecki (talk) 13:14, 23 March 2022 (UTC)
- I provided refs for the two enzymes in the lead (removed Oregon State and used two existing refs from the body of the article) David notMD (talk) 18:40, 25 March 2022 (UTC)
- I assume good faith on offline references I didn't access in my spot check; other issues were addressed. Szmenderowiecki (talk) 19:33, 25 March 2022 (UTC)
