Porphobilinogen
Biosynthesis In the first step of the porphyrin biosynthesis pathway, porphobilinogen is generated from aminolevulinate (ALA) by the enzyme ALA dehydratase Metabolism In the typical porphyrin biosynthesis pathway, four molecules of porphobilinogen are concatenated by carbons 2 and 5 of the pyrrole ring (adjacent wikipedia.org

Asymmetric porphyrin solar cell dye and preparation ... - Semantic Scholar
The invention relates to an asymmetric D-PI-A type dye and an intermediate material used for a dye-sensitized solar cell and taking porphyrin as a core, and a synthetic preparation method and an application of the dye. In a molecular structure of the dye, donators of alkane and alkoxy in different carbon chain lengths, triple-bond receptors are asymmetrically substituted at the periphery of a ...

Cobalt(II)–porphyrin catalysis
Cobalt(II)–porphyrin catalysis is a process in which a Co(II) porphyrin complex acts as a catalyst, inducing and accelerating a chemical reaction. Co(II)–porphyrin catalysts lack vacant cis-coordination sites available (all occupied). wikipedia.org

Abelsonite
Abelsonite is a nickel porphyrin mineral with chemical formula C31H32N4Ni. It was discovered in 1969 in the U.S. The mineral is a deoxophylloerythroetioporphyrin (DPEP), with nickel occupying the center of the porphyrin ring. wikipedia.org

Hexaminolevulinate
Hexaminolevulinate is a structural analogue to 5-aminolevulinic acid (a precursor to the porphyrin ring of heme), and is internalized and processed into After exposure to 360-450 nm light, the porphyrin will fluoresce red. References Oncology Optical imaging wikipedia.org
