Chlorophyll

Chlorophyll is the green pigment found in the chloroplasts of plant cells, primarily responsible for absorbing sunlight during the process of photosynthesis. Structurally, chlorophyll molecules are characterized by a porphyrin ring with a magnesium ion at the center, which plays a crucial role in capturing light energy.

Chlorophyll does not have a strong distinct scent. However, the general odor associated with chlorophyll-rich materials such as crushed green leaves or freshly cut grass is often described as "green" or "earthy." These scents are attributed to a mixture of compounds released when plant cells are damaged, rather than to chlorophyll itself. Key contributing compounds include isoprene, hexenal, and other green leaf volatiles, which create a fresh, natural, and sometimes slightly bitter aroma. This fresh plant scent is often associated with cleanliness and crispness, reflecting the invigorating essence of nature and open green spaces.
