WebChlorophyll is essentially two parts: a substituted porphyrin ring and phytol (the long carbon chain). The porphyrin ring is an excellent chelating ligand, with the four nitrogen atoms binding strongly to a co-ordinated metal atom in a square planar arrangement. There are many examples of this including heme and vitamin B 12. WebDec 30, 2024 · For example, chlorophyll a has absorption peaks at approximately 430 and 662 nm, whereas chlorophyll b has peaks at 453 and 642 nm. The difference between the two is small: at C7, there is a —CH 3 group on chlorophyll a, but a —CHO group on chlorophyll b. Presently, there are five known chlorophylls: chlorophyll a is found in all ...
