• Description: Chlorophyll is the green pigment in plants that allows them to create energy from light – to photosynthesize. Chlorophyll A and B are two major types of chlorophyll found in plants and green algae. Both are involved in the process photosynthesis. Both chlorophyll A and B are found in chloroplasts, associated with integral membrane proteins in the thylakoid membrane. The main difference between chlorophyll A and B is their role in photosynthesis? chlorophyll A is the principal pigment involved in the photosynthesis whereas chlorophyll B is the accessory pigment, collecting the energy in order to pass into chlorophyll A. In chlorophyll A, the most effectively absorbing wavelengths of the spectrum are 429 nm and 659 nm, which are responsible for violet-blue and orange-red colors, respectively.
• Uses: Chlorophyll A is a photosynthetic pigment that is essential for photosynthesis of eukaryotes and cyanobacteria, acting as a primary donor in the electron transport chain. Dyes and metabolites.
