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

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

    Abstract : 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. READ MORE

  4. 2. Calcium transporting ATPases in plant cells

    Author : Malin Olbe; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Triticum aestivum; calcium; Brij 58; calmodulin; Ca2 signalling; inside-out; endoplasmic reticulum; plant; plasma membrane; proteolysis; P-type ATPase; spinach; Spinacea oleracea; trypsin; two-phase; wheat.; Plant biochemistry; Växtbiokemi;

    Abstract : Plant cells carry Ca2+ ATPases to maintain the low resting level of cytosolic Ca2+ (0.1-0.2 µM) found in all eukaryotes. Plant Ca2+ ATPases are mainly located in the plasma membrane, the endoplasmic reticulum and in the vacuolar membrane, and consequently large Ca2+ gradients are created across these membranes.

  5. 3. The xanthophyll cycle, its enzymes, pigments and regulation

    Author : Marie Eskling Carlsson; Biokemi och Strukturbiologi; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; zeaxanthin; xanthophyll cycle; violaxanthin de-epoxidase; thylakoid; spinach; regulation; purification; pigments; photoprotection; pH dependence; ascorbate; light stress; Plant biochemistry; Växtbiokemi;

    Abstract : The xanthophyll cycle involves the light-dependent and reversible conversion of violaxanthin to zeaxanthin. Zeaxanthin has been implicated in the protection of the photosynthetic machinery from over-excitation. The enzyme violaxanthin de-epoxidase catalyses the conversion of violaxanthin to zeaxanthin.

  6. 4. Vacuum Impregnation of Spinach Tissue: Metabolic Consequences and their Potential Industrial Applications

    Author : Noor Liyana Yusof; Avdelningen för livsmedel och läkemedel; []
    Keywords : Vacuum impregnation; Metabolic consequences; Spinach : metabolism; Modified atmosphere; Minimal processing; Nitrate reduction; Vegetables; Plant tissue;

    Abstract : Vacuum impregnation (VI) is a unit operation that allows the introduction of solutions into the porous structure of plant tissues. The plant tissue is immersed in the solution of interest and is then subjected to partial vacuum, causing the removal of air from the tissue. READ MORE

  7. 5. Studies on spinach plastocyanin and mutants : Expression in Escherichia coli, folding and function

    Author : Mikael Ejdebäck; Örjan Hansson; Miguel A. De la Rosa; Göteborgs Universitet; []
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; plastocyanin; electron transfer; copper; protein-protein interactions; protein expression; folding; site-directed mutagenesis; NMR; Naturvetenskap; Natural sciences;

    Abstract : Photosynthesis is a process in which photons from sunlight excite chlorophylls in the thylakoid membranes of plants, algae and cyanobacteria. The photo-oxidised reaction centre chlorophyll P700 is re-reduced by an electron transferred from the soluble, blue copper protein plastocyanin. READ MORE
