DURING experiments on pigment orientation in chloroplasts and grana, it was necessary to determine the directions in which linearly polarized light is preferably absorbed in a pigment molecule.

The high resolution structure of photsystem I reveals an ... however are also important for protecting against photodamage of chlorophyll molecules — they quench the triplet state of ...

Yagai. To create these structures, the team modified the chlorophyll molecule by attaching a barbituric acid unit via hydrogen bonding and further added tree-like molecular structures called ...

Their structures are very different, for example: plants have stems, roots, flowers, and fruits, while algae do not. And where plants are always made of many cells, algae may be made from one single ...

Researchers often look to photosynthesis—a process that turns sunlight into chemical energy in plants and bacteria—as a model for innovation. Photosynthesis is in turn linked to chlorophyll pigments, ...
