General description
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.
Application
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
Biochem/physiol Actions
Chlorophyll a binds to the protein molecules CP47 and CP43, forming the inner antenna of the reaction center of Photosystem II. In photosystem I, the binding sites of chlorophyll a includes the polypeptides spread across the membranes. Scarcity in formation of chlorophyll and a low chlorophyll density can lead to deficiency of nitrogen in plants leaves.
