Chlorophyll occurs in several distinct forms: chlorophylls a and b are the major types found in higher plants and green algae; chlorophylls c and d are found, often with a, in different algae; chlorophyll e is a rare type found in some golden algae; and bacterio-chlorophyll occurs in certain bacteria. Dai R, Shoemaker R, Farrens D, et al. STATE: Solid. The magnesium center uniquely defines the structure as a chlorophyll molecule. The intense green color of chlorophyll is due to its strong absorbencies in the red and blue regions of the electromagnetic spectrum, … (A) Reactions of the first part of the pathway from chlorophyll to hydroxy-pFCC that take place inside the chloroplast.Pyrrole rings are labelled A–D and relevant atoms are indicated in a porphyrin (chlorophyll a) and a phyllobilin (pFCC).
