[edit] divalent

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 (talkcontribs).

Looks like you are right. --Dirk Beetstra T C 18:31, 10 January 2007 (UTC)

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... R.Wimmer 2.10.2007 —Preceding unsigned comment added by 138.245.59.58 (talk) 14:00, 2 October 2007 (UTC)
