Its principal type is a chelate of a dihydroporphyrin with a cyclopentanone ring and is esterified with phytol. The alicyclic 5-membered cyclopentanone ring, which contains a carbonyl group at position 9, is unique to these compounds. Both Tribonema and Vaucheria have been used to isolate the "e" type, and all types are synthesized beginning with glycine and succinic acid and ending in a magnesium chelate. It is now known that cyanobacteria contain the "a" type of FTP, what absorbers of light quanta, a set of green pigments involved in photosynthesis.
