Durning senescence, this compound is metabolized into tetrapyrrole catabolites known as NCCs. Though not heme, it is often synthesized from succinyl-CoA and glycine, and it often includes a long phytol chain. Consisting of a [*] porphyrin coordinated to an atom of magnesium, the a and b varieties absorb light at slightly different wavelengths, and it can be found in the thylakoids.  For 10 points,
