  1. 1. Food ingredients from cultivated seaweeds-Improving storage stability and protein recovery

    University dissertation from Gothenburg : Chalmers tekniska högskola

    Author : Hanna Harrysson; [2019]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; alterative cultivation; pH-shift; proteins; lipid oxidation; protein extraction; unsaturated fatty acids; ascorbic acid; long-term storage; sequential recovery; Seaweed; macroalgae;

    Abstract : There is a global demand for new vegetarian protein sources, and seaweed have for multiple reasons been identified as a promising candidate. The overall aim of this thesis was to evaluate the potential of three different Swedish seaweed species as food protein sources, but also as sources of unsaturated fatty acids, vitamins and minerals.

  2. 2. Biochemical Control Aspects in Lignin Polymerization

    University dissertation from Stockholm : KTH

    Author : Anders Holmgren; KTH.; [2008]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Lignin polymerization; DHP; Ascorbic Acid; NADH; template polymerization; melanin; NATURAL SCIENCES Chemistry; NATURVETENSKAP Kemi;

    Abstract : Lignins are produced by all vascular plants and they represent one of the most abundant groups of biopolymers in nature. Lignin chemistry research, which has been of great importance for the progress of pulping technologies, has been plagued by the difficulties of its isolation and characterization. READ MORE

  3. 3. Extracellular Glutathione Peroxidase - Purification, Immunoassay, Nutritional Regulation and Clinical Aspects

    University dissertation from Department of Applied Nutrition and Food Chemistry, Lund University

    Author : Wenhu Huang; [1996]
    Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; Antioxidant enzymes; Ascorbic acid; Parenteral nutrition; Selenium intake; Radioimmunoassay; Selenoproteins; Glutathione peroxidase; Cataract; Proteins; enzymology; Proteiner; enzymologi;

    Abstract : Extracellular glutathione peroxidase (eGSHPx) is a selenoprotein catalysing the reduction of hydrogen peroxide, organic peroxides and lipid peroxides in the presence of glutathione. A scaled-up purification procedure for obtaining eGSHPx from human plasma was established based on ammonium sulphate fractionation, hydrophobic interaction chromatography, ion-exchange chromatography and gel chromatography.

  4. 4. Reactions of Model and Anticancer Active Platinum(IV/II) Complexes - A Kinetic and Mechanistic Study

    University dissertation from Inorganic Chemistry, Chemical Center, Lund University

    Author : Kelemu Lemma; [2001]
    Keywords : NATURVETENSKAP; NATURAL SCIENCES; Model Pt II complexes; Anticancer active Pt IV compounds; Cisplatin; Rescue agents; L-Ascorbic acid; Thiol; Substitution; Kinetics and mechanism; Electron transfer; Inorganic chemistry; Oorganisk kemi;

    Abstract : In this thesis reductions of model and anticancer active Pt(IV) complexes with thiols and ascorbic acid and substitution reactions of cisplatin and model Pt(II) complexes with S-donor nucleophiles (rescue agents) have been investigated using stopped-flow and UV/VIS spectrophotometry. Glutathione (GSH) reduction of the anticancer active Pt(IV) compounds t- and c-[PtCl4(cha)(NH3)] (cha = cyclohexylamine), t-[PtCl4(thiazole)(NH3)] and c-[PtCl4(NH3)2] at 25 oC was observed to be very fast.

  5. 5. Nutritional Value and Quality of Processed Mango Fruits

    University dissertation from Inorganic Chemistry, Chemical Center, Lund University

    Author : Isabel Guiamba; [2016]
    Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; acidification; ascorbic acid oxidase; polyphenoloxidase; water blanching; β-carotene; osmotic dehydration; infrared heating; microwave heating; Mango; EDTA; vitamin C;

    Abstract : Mango (Mangifera indica L.) is one of the most important tropical fruits commercialized and consumed worldwide, and an excellent source of fibre, bioactive compounds such as pro-vitamin A carotenoids, vitamin C (ascorbic acid) and phenolics. Mango was used in this thesis as a model fruit of fruits and vegetables that are rich sources of nutrients. READ MORE
