There are mainly two types of chlorophyll, named a and b, which differ in the composi­tion of a side chain (in a it is -CH 3, while in b it is CHO). Chlorophyll's role is to absorb light for photosynthesis. Chlorophyll B's role is to help organisms absorb higher frequency blue light for use in photosynthesis. A divalent central magnesium is attached with the nitrogen atoms of the four pyrrol rings. The name comes from a combination of two Greek words, chloros, meaning "green" and phyllon, meaning "leaf." (1991) and the peak locations were determined in the UV-Vis application (Figure 1). The reflecting color of chlorophyll A is a blue-green color.
