Chlorophyll a is an important light-harvesting, green or blue color pigment present in the photosynthetic membranes of the chloroplasts in plant cells. It functions as an antenna pigment in photosystems I and II.A procedure has been described for harvesting native light-harvesting complex IIb (LHCIIb).Chlorophyll a has been used:to study the variation in carotenoids composition with changing colors and maturation in soybean seeds;to examine the use of chlorophyll distribution maps obtained from hyperspectral imaging for the non-destructive diagnosis of Nitrogen deficiency;as a standard to determine the concentration of the analyte by fluorescence spectrophotometric technique in the water sample collected from the yellow river;as a standard to quantify the amount of chlorophyllous pigments gathered from algae by high performance liquid chromatographic (HPLC) technique;in the identification of pheophytin a from environmentally friendly cultivated green peppers;to sense different nitric oxide (NO) species.
