P700, or photosystem I primary donor, is a molecular dimer of chlorophyll a associated with the reaction center of photosystem I in plants, algae, and cyanobacteria.
== Etymology == Its name is derived from the word pigment (P) and the presence of a major bleaching band centered around 695–700 nm in the flash-induced absorbance difference spectra of P700/P700+•.
