1. Quantum Chemical Studies of Protein-Bound Chromophores, UV-Light Induced DNA Damages, and Lignin Formation
Sammanfattning : Quantum chemical methods have been used to provide a better understanding of the photochemistry of astaxanthin and phytochromobilin; the photoenzymic repair of UV-light induced DNA damages; and the formation of lignin. The carotenoid astaxanthin (AXT) is responsible for the colouration of lobster shell. LÄS MER
2. Structure, dynamics and reactivity of low-oxidation state iron complexes in solution studied by ab initio molecular dynamics simulations and advanced quantum chemistry calculations
Sammanfattning : Third row (3d) metals, such as iron have become a candidate for a broad class of photocatalysts that have a large abundance on Earth and a low toxicity to humans and the environment. Unlike many commonly used photocatalysts that contain expensive precious metals, iron is cheap. LÄS MER
3. Computational Studies of Photobiological Keto-Enol Reactions and Chromophores
Sammanfattning : This thesis presents computational chemistry studies of keto-enol reactions and chromophores of photobiological signicance.The rst part of the thesis is concerned with two protein-bound chromophores that, depending on the chemical conditions, can exist in a number of dierent ketonic and enolic forms.

4. Photochemical properties of phytochrome and firefly luciferase chromophores: A theoretical study
Sammanfattning : This licentiate thesis presents computational chemistry studies on photochemical properties of phytochrome and firefly luciferase chromophores.Phytochromes are bilin-containing proteins that based on the ambient light environment regulate a number of physiological and developmental processes in bacteria, cyanobacteria, fungi and plants.
