Summary
The compression of mixtures of photosynthetic pigments and phosphatidylcholine in monolayers at a water-air interface shows that (i) the phosphatidylcholine disperses the isolated pigment molecules; (ii) chlorophyllsa andb, chlorophylla and β-carotene, and chlorophyllb and β-carotene form associations which cannot be undone by the phospholipids; and (iii) when the two chlorophylls and β-carotene are mixed all together with or without phosphatidylcholine, the three types of associations are ideally mixed and they can be dispersed by phosphatidylcholine.
