[edit] PubChem unreliable here

This is difficult to get right. I relied on PubChem for a lot of the chem info; it's usually a good source:

But here it's all messed up. They've got pinolenic equivalent to columbinic; and they show both of them as all trans. All the other literature says that pinolenic is all cis and columbinic is trans/cis/cis. If they're right—most everything else I turn up with Google scholar is wrong.David.Throop 03:42, 26 October 2007 (UTC)

PubChem has many errors. The database is generated from third-party submissions and there doesn't seem to be a high degree of quality control. You are definitely better off doing as you have done and relying on the primary literature. --Ed (Edgar181) 20:35, 28 October 2007 (UTC)
