Types of Chlorophyll
The 6 different types of Chlorophyll
There are 6 different types of Chlorophyll pigment that have been identified by famous chemists including Richard Willstätter, Hans Fischer, Robert Burns Woodward and Ian Fleming. Their structures are based on a chlorin ring at the center of which is a magnesium ion. The structure can have different side chains depending on the type of Chlorophyll.
1) Chlorophyll a
Chlorophyll a is the most widely occurring and universal type of Chlorophyll. It is found in plants, algae and many other aquatic organisms. Chlorophyll a's molecular structure consists of a chlorin ring with Mg center. It also has side chains and a hydrocarbon trail. It absorbs light from red, blue and violet wavelengths and gets its color by reflecting green.
2) Chlorophyll b
Chlorophyll b is a type of Chlorophyll that is mostly found in plants. It aids the process of photosynthesis and primarily it absorbs blue light. The pigment itself is yellow in color. Similar to Chlorophyll a, Chlorophyll b's molecular structure has a 4-ion Nitrogen ring with Mg center, with side chains and hydrocarbon trail.
3) Chlorophyll c1
Chlorophyll c1 is actually an accessory pigment that works in conjunction with Chlorophyll a to absorb light and aid photosynthesis. This type of Chlorophyll has a brownish or golden color and is found mostly in marine algae. The molecular structure of Chlorophyll c1 consists of a Chlorin ring but does not have a tail.
4) Chlorophyll c2
Similar to Chlorophyll c1, Chlorophyll c2 is mostly found in marine and freshwater algae. Its molecular structure has a 4 ion Nitrogen ring and Mg center but does not have a tail.
5) Chlorophyll d
Identified comparatively recently 1996, Chlorophyll d is a type of Chlorophyll that absorbs light which is in the extreme red end of the light spectrum. This type of light is known as far-red light and is just beyond the visible optical range, before infra-red. The natural occurrence of Chlorophyll d is found only in Acaryochloris marina, a type of Cyanobacteria.
6) Chlorophyll f
Chlorophyll f absorbs infra-red light, from most extreme end of red spectrum. Not much is known about Chlorophyll f's occurrence in nature except that it is found in Cyanobacteria which are a part of algae found in shallow waters. Chlorophyll f's exact function in the process of photosynthesis is also uncertain.
