Structure of the protein subunit in the photosynthetic reaction centre of Rhodopseudomonas viridis at 3 Å resolution.
Discovery of the three-dimensional structure of a protein complex found in certain photosynthetic bacteria, called the photosynthetic reaction center. This was the first elucidation of the 3D crystal structure of any …

Zur Kenntnis des Vitamins-A aus Fischtranen.
In 1930 Karrer established the correct formula for carotene (the chief precursor of vitamin A), the first demonstration of the chemical structure of a vitamin. Shortly thereafter, he was able to determine the formula …
