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. --

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

I rewrote the article because there were too many mistakes to correct it in other way. R.L.

Oxidized P680 (P680+) is the strongest biological oxidizing agent known???? But it's already been oxidized. — Preceding

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. --

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.--
