Wikipedia:Peer review/Percy Lavon Julian/archive1

Please help review the article for Black History Month

It's a pretty decent article, but I have a few suggestions:

I think commas would be helpful here: "...discovered that, upon hydrolysis, soy protein acted..." Just my opinion of course.
casein could be linked.
There's no mention of the difficulties Percy Julian experienced with his Mexico plant (in which he was heavily invested), or of the outcome of his struggles there.
If possible I would like to see more about his work at Julian Laboratories.
It would be good to see an estimate of the number of his scientific publications in journals and such.
It's a minor issue, but there are a few spaces between punctuation and the citation links. It would look tighter if those were removed.
