Chlorophylls, Symmetry, Chirality, and Photosynthesis

Chlorophylls are a fundamental class of tetrapyrroles and function as the central reaction center, accessory and photoprotective pigments in photosynthesis. Their unique individual photochemical properties are a consequence of the tetrapyrrole macrocycle, the structural chemistry and coordination behavior of the phytochlorin system, and specific substituent pattern. They achieve their full pote...

Chlorophylls - Natural Solar Cells

A molecular modeling study was conducted on a series of six natural occurring chlorophylls. Quantum chemistry calculated orbital energies were used to estimate frequency of transitions between occupied molecular orbital and unoccupied molecular orbital energy levels of chlorophyll molecules in vivo conditions in standard (ASTMG173) environmental conditions. Obtained results are in good agreemen...

Contents of Chlorophylls a and b in Chlorophyll-Deficient Mutants of Sweetclover

Leaf extracts from twelve chlorophyll-deficient mutants of sweetc10ver (Melilotus alba Desr_) were compared spectrophotometrically and chromatographically with extracts from normal plants to determine contents of chlorophylls a and b_ Total chlorophyll contents in cotyledons and leaves of all mutants were significantly lower than those in corresponding tissues of normal plants_ Chlorophyll cont...
