Quick Summary

Chlorophyll b is a pigment crucial for photosynthesis, the process where light energy is converted into chemical energy. It is primarily found in higher plants and green algae, working alongside chlorophyll a.123

Chlorophyll molecules, including chlorophyll b, consist of a central magnesium atom within a porphyrin ring, attached to a phytol chain. Chlorophyll b differs from chlorophyll a through minor modifications in its side groups. These pigments absorb light energy, which is then used to convert carbon dioxide into carbohydrates. Chlorophyll b is located within the chloroplasts of plant cells, specifically in the thylakoid membranes.13
