An O 2 ‐evolving photosystem II (PSII) fraction was isolated from spinach chloroplasts using Triton X‐100. The distribution of polar lipids is different from that in thylakoids: the ratio monogalactosyldiacylglycerol/digalactosyldiacylglycerol being higher and the level of sulfoquinovosyldiacylglycerol being lower in the PSII fraction. A large amount of phosphatidylglycerol containing trans ‐Δ 3 ‐hexadecenoic remains associated to the PSII fraction. A possible role for molecules of phosphatidylglycerol containing trans ‐Δ 3 ‐hexadecenoic acid in the regulation of energy transfer between the two photosystems is suggested.
