Ferrocheletase is needed to synthesize them in humans.
Alfred Treibs isolation of these compounds from petroleum created the field of organic geochemistry. Atsuhiro Osuka's group polymerized 1024 of these molecules in order to create a giant antenna. Intense absorption around 410 nm known as the Soret peak is characteristic for these compounds, whose mesotetraphenyl variety can be synthesized by refluxing methylbenzaldehyde and pyrrole under propionic acid reflux. Ferrocheletase is needed to synthesize them in humans. Humans synthesize them by combining succinyl-CoA with glycine in order to form alpha-aminolevulinic acid. Pheophytin contains one of them, though more famously they are coordinated to iron in heme. For 10 points, name these large cyclic compounds which contain four pyrroles coordinated to a central metal atom, found in chlorophyll.
