Let me share with you a comparison between Chlorophyll a and Chlorophyll b.
| Aspect | Chlorophyll a | Chlorophyll b |
| Chemical formula | C55H72O5N4Mg | C55H70O6N4Mg |
| Absorption peaks | Absorbs light most efficiently in the red and violet-blue range of the spectrum. | Absorbs light most efficiently in the blue and red-orange range of the spectrum. |
| Color | Appears blue-green. | Appears yellow-green. |
| Role in Photosynthesis | Primary pigment involved in the conversion of light energy into chemical energy during photosynthesis. | Acts as an accessory pigment, capturing light energy and transferring it to chlorophyll a. |
| Function in light Absorption | Captures light energy and converts it into chemical energy through photosynthesis. | Expands the range of light absorption, helping to capture light energy in regions where chlorophyll a is less effective. |
| Structural differences | Lacks an aldehyde group in its structure. | Contains an aldehyde group in its structure. |
