divalent
[edit]Since Ca2+ is (obviously) divalent, and each carboxylate is monovalent, I'd guess that each end of the molecule binds to one Ca2+ ion, thus each molecule of BAPTA only binds two Ca2+ ions, and not four as is suggested in the article. That's just my chemical intuition, though, and I don't have any evidence, really to support that.—The preceding unsigned comment was added by Alkaloids (talk • contribs).

BAPTA is a chelating agent and binding to the central ion is not a ionic binding but rather due to delocalized electron pairs. So only one Ca++ is bounded as confered to EDTA, EGTA...

I'm not seeing the reference to BAPTA in the 1st citation. just a note. —Preceding unsigned comment added by 144.62.212.167 (talk) 01:21, 14 October 2010 (UTC)
