Definition
Chlorophyll b is a species that is generally characteristic of higher plants and is an accessory chlorophyll that occurs in green algae. Its salts are essential in nutrition, being required for the activity of many enzymes, especially those concerned with oxidative phosphorylation. It is a component of both intra- and extracellular fluids and is excreted in the urine and feces.
General Description
Chlorophyll b is one of the chlorophyll pigments that impart leaves their green color. Chlorophyll is a Greek name with?chlorós?meaning green and?phyllon?meaning leaf. It is present in peripheral antenna complexes along with chlorophyll a. The amount of chlorophyll b in spinach is found to be lesser than chlorophyll a.
Biochem/physiol Actions
Chlorophyll b undergoes breakdown to form pheophytin b by the enzyme chlorophyllase. This causes a change in its color from green to olive-brown. It is involved in the harvesting of light energy during the process of photosynthesis and its subsequent conversion to chemical energy. Along with chlorophyll a, it plays a key role in the ability of a plant to adapt to different light intensities.
Purification Methods
It forms red-black hexagonal bipyramids or four-sided plates from dilute EtOH and has been recrystallised from CHCl3/MeOH. It is soluble in MeOH, EtOH, EtOAc and insoluble in pet ether. [Dougherty et al. J Am Chem Soc 88 5037 1966, Beilstein 26 III/IV 3787.]
Check Digit Verification of cas no
The CAS Registry Mumber 519-62-0 includes 6 digits separated into 3 groups by hyphens. The first part of the number,starting from the left, has 3 digits, 5,1 and 9 respectively; the second part has 2 digits, 6 and 2 respectively.
Calculate Digit Verification of CAS Registry Number 519-62:
(5*5)+(4*1)+(3*9)+(2*6)+(1*2)=70
70 % 10 = 0
So 519-62-0 is a valid CAS Registry Number.

, p. 1048 - 1067 (2007/10/02)
Experimental details are given for the new method of introducing magnesium into porhpinoid ligands by (2,6-di-t-butyl-4-methylphenoxy)magnesium iodide (1), previously published in preliminary form .Besides magnesium octaethylporphyrinate (14), methyl pyrochlorophyllide a (10), methyl chlorophyllide a (8), and methyl bacteriochlorophyllide a (12), the complexation of pheophytin a (2) to chlorophyll a (3) and of pheophytin b (4) to chlorophyll b (5) are described.
