- This could do with some context for those who know nothing of the subject. m.e. 05:08, 2 November 2006 (UTC)
- Added LHCII and corrected the fact that there are 2 chlorophyll a molecules per P680. None the less the primary electron acceptor is a feofytin, problem is this molecule doesn't seem to exist in english. Anny help about it's english name please. It's feofytine in Dutch and feofytin in German and such. -- Snelleeddy 21:18, 27 May 2007 (UTC)
- It should be pheophytin. —Preceding unsigned comment added by Kasper90 ( talk • contribs) 20:36, 18 September 2008 (UTC)
- This article isn't right. The 'P' in P680 doesn't stand for Photosystem, but for Pigment. P680 is just one pigment and not a whole photosystem. —Preceding unsigned comment added by 94.210.174.187 ( talk) 19:56, 17 September 2008 (UTC)
- I rewrote the article because there were too many mistakes to correct it in other way. R.L. 147.231.252.83 ( talk) 12:53, 19 September 2008 (UTC)
- Oxidized P680 (P680+) is the strongest biological oxidizing agent known???? But it's already been oxidized. — Preceding unsigned comment added by 66.103.120.175 ( talk) 17:43, 13 November 2011 (UTC)
- The article seems to imply that P680 always acts as a dimer, but I think details from this article from the Journal of Photochemistry and Photobiology A: Chemistry with information about the structure and functioning of P680 needs to be considered: " P680, the primary electron donor of photosystem II" The article indicates that P680 is not a special pair and is made up of four weakly interacting chlorophylls. -- 18.111.59.56 ( talk) 14:05, 10 March 2015 (UTC)
- The already cited article from Raszewski from 2008 says otherwise. PD1 and PD2 from the special dimer have a very short distance and are slightly tilted out of the coplanar plane. Raszewski mention, that this is the reason for it's enormous high redox potential. Knapp et al. ( Ishikita, 2005) showed in calculations of the redox potential of various components in P680, that the charge most likely resides directly after excitation upon chlD1, before relaxing and forming the exciton [PD1/PD2•+ Pheo•-. So the special pair can be seen as one reaction center, forming together with two addition chlorophyls the pigment 680.-- 134.61.103.46 ( talk) 11:45, 29 October 2015 (UTC)
