   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; chlorin; hydroporphyrin; chlorophyll analogues; light harvesting; lanthanide luminescence; Chemistry with specialization in Organic Chemistry; Kemi med inriktning mot organisk kemi;

   Sammanfattning : Chlorins, as the core structures of chlorophylls, have been extensively studied for harvesting solar energy, fluorescent imaging and photodynamic therapy against cancer. This thesis is concerned with design and synthesis of novel chlorins as antennae for harvesting light and sensitising near infrared lanthanide luminescence. LÄS MER

3. 2. Preparation of leaf mitochondria and studies on mitochondrial photorespiratory reactions

   Författare :Per Gardeström; Umeå universitet; []
   Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; leaf mitochondria; photorespiration; aqueous two-phase system; Percoli gradient; cytochromes; glycine decarboyxlase; serine hydroxymethyltransferase; inhitors of photorespiration;

   Sammanfattning : A procedure for the preparation of spinach leaf mitochondria was developed. The procedure combines differential centrifugation, partition in dextran- polyethyleneglycol two-phase system and Percoli density gradient centri- fugation. The different steps separate the material mainly according to size, surface properties and density, respectively. LÄS MER
