  1. 1. Protein complexes in chlorophyll biosynthetic enzymes

    Författare :Ragna Peterson Wulff; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; electron microscopy; mass spectrometry; Rhodobacter capsulatus; barley; cyclase; magnesium chelatase; chlorophyll biosynthetic pathway; Protein complex;

    Sammanfattning : Proteins are found on the inside, in the membrane, on the surface and on the outside of cells. They form complicated structures and they interact with other molecules and proteins. LÄS MER

  2. 2. Magnesium Chelatase - a Key Enzyme in Chlorophyll Biosynthesis

    Författare :Eva Axelsson; Biokemi och Strukturbiologi; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; Kemi; Chemistry; AAA-proteins; Chlorophyll biosynthesis; Magnesium chelatase;

    Sammanfattning : The biosynthesis of chlorophylls is an important process in nature. The green pigments play a fundamental role in absorbing and transferring solar energy to the photosynthetic apparatus. LÄS MER

  3. 3. Ultrafast Dynamics in Ground and Excited States of Porphyrin Molecules

    Författare :Peter Martinsson; Kemisk fysik; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; intra- and intermolecular dynamics.; Zn-porphyrin; bacteriochlorophyll a; chlorophyll b; Femtosecond transient absorption spectroscopy; chlorophyll a; Physical chemistry; Fysikalisk kemi;

    Sammanfattning : This thesis describes inter and intramolecular dynamics in porphyrin molecules. To create a basis for understanding the energy and electron transfer processes in photosynthesis, the ultrafast dynamics of monomeric chlorophyll a, chlorophyll b and bacteriochlorophyll a were studied with ultrashort laser pulses.

  4. 4. Thylakoid membrane from spinach - effect of processing on their function as appetite suppressing ingredient

    Författare :Karolina Östbring; Aptitkontroll; []
    Nyckelord :MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Drying; Storage Conditions; Appetite; Thylakoids; Heat treatment; Chlorophyll; Spinach;

    Sammanfattning : Western diet contains a high proportion of palatable food, rich in refined carbohydrates and fat, that subsequently increases the risk of overconsumption and possibly leads to overweight and obesity. Therefore an approach to strengthen the inherent satiety for fat can be used to prevent overconsumption. LÄS MER

  5. 5. Iron nutrition dynamics - Differences between calcicole and calcifuge plants

    Författare :Angelika Zohlen; Biologiska institutionen; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; 10-phenanthroline; 1; chlorophyll; plaque; root; leaf; immobilization; plants; calcifuge; Iron; calcicole; Plant ecology; Växtekologi;

    Sammanfattning : One third of the earth´s soils is calcareous. Calcifuge plants are excluded from these soils, and one of the main causes is Fe deficiency, as Fe solubility in calcareous soil is very low. A lack of Fe lowers chlorophyll content, visible as yellowing of leaves, called chlorosis. LÄS MER
