CLASSIFICATION

  

GENERAL DESCRIPTION OF CHLOROPHYLL & CHLOROPHYLLIN
Chlorophyll is the generic name for several fat-soluble green plant pigments which includes the open-chain bile pigments and the large ring compounds. The structure of chlorophyll molecule has four nitrogen-containing pyrrole rings bonded to a central magnesium atom, and the fifth ring containing only carbon atoms, and various long hydrocarbon tails attached to the pyrrole rings. The molecular structure of the chlorophylls is similar to that of the heme bound to proteins forming hemoglobin, except that the latter contains iron(II) ion in the center of the porphyrin. Chlorophyll a and b are the most common of the several chlorophyll molecules. Chlorophylls a  is a waxy blue-black microcrystalline green-plant pigment, C55H72MgN4O5, with a characteristic blue-green alcohol solution. Chlorophyll a occurs in all organisms exhibiting aerobic photosynthesis (green plants, algae, and cyanobacteria). Chlorophyll b, occurs in higher plants, is a similar green-plant pigment, C55H70MgN4O6, having a brilliant green alcohol solution. There are chlorophylls c1 and c2 in diatoms and brown algae, and chlorophyll d in red algae.

Chlorophyll a

Chlorophyll b
Chlorophyllin is a water-soluble salt obtained by alkaline hydrolysis of chlorophyll with replacement of the magnesium by copper and methyl and phytyl ester groups by sodium and potassium. Preparations of the salts are applied topically for the deodorization of skin lesions and administered orally to deodorize ulcerative skin lesions and the urine and feces in colostomy, ileostomy, or incontinence. Chlorophyll absorbs visible radiation in the blue-violet and red regions of the electromagnetic spectrum; the green portion is not absorbed and transmitted and reflected, resulting in the green color appearance of plant leaves. Chlorophyll plays an important role in the conversion of sunlight into chemical energy in the process of photosynthesis.  In this biochemical process, the energy absorbed by chlorophyll transforms carbon dioxide obtained from air and water absorbed by the roots into plant food, carbohydrates and waste product of oxygen which, however, is released into the environment for most life. The other plant pigments involved in light harvesting and energy transfer in photosynthesis are carotenoids, phycobilin, or phycoerythrin which become apparent when the amount of chlorophyll decreases and show the other colors.

APPLICATIONS

The intense color of chlorophyll is useful as a commercial pigment. It is used as a green dye for food, toothpaste, detergents and cosmetics. It has chelating agent activity also. It is used in ointment, pharmaceutical (especially liver recovery and ulcer treatment). It is applicable in luminescence chemistry, spectrophotometric analysis as well as organic synthesis and polymerization catalyst.
