product name:chlorophyll B
CAS:*******0
Description:Chlorophyll b is a form of chlorophyll. Chlorophyll b
helps in photosynthesis by absorbing light energy. It is more
soluble than chlorophyll a in polar solvents because of its
carbonyl group. Its color is yellow, and it primarily absorbs blue
light.
In land plants, the light harvesting antennae around photosystem II
contain the majority of chlorophyll b. Hence, in 'shade adapted
chloroplasts', which have an increased ratio of Photosystem II to
Photosystem I, there is a lower ratio of chlorophyll a to
chlorophyll b (Kitajima and Hogan ***3). This is adaptive as
increasing chlorophyll b increases the range of wavelengths
absorbed by the shade chloroplasts.
