  3. 2. Sustainable Biobased Protein Superabsorbents from Agricultural Co-Products

    Författare :Antonio Jose Capezza; Mikael S. Hedenqvist; Eva Johansson; Antonio Guerrero; KTH; Sveriges lantbruksuniversitet; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; NATURVETENSKAP; NATURAL SCIENCES; proteins; circularity; superabsorbents; sustainability; acylation; extrusion; Fiber- och polymervetenskap; Fibre and Polymer Science;

    Sammanfattning : The preparation of sustainable protein superabsorbents from agricultural industry side-streams is reported. Wheat gluten (WG), a co-product from the ethanol/starch industry, was processed into foams with sponge-like behavior and high liquid uptake. LÄS MER

  4. 3. LIPASES AND PHOSPHOLIPASES IN PHOSPHOLIPID SYNTHESIS

    Författare :Carmen Virto; Bioteknik; []
    Nyckelord :TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; transphosphatidylation; acylation; vinyl ester; Phospholipid synthesis; lysophospholipid; kinetics; Biotechnology; Bioteknik;

    Sammanfattning : The synthesis of phospholipids with defined fatty acid and polar head composition catalysed by lipases and phospholipases was investigated. Lipases from Rhizopus arrhizus and Candida antarctica were used for the direct acylation of DL-a-glycerophosphate and L-a-glycerophosphatidylcholine, with different fatty acids. LÄS MER

  5. 4. Development of Aerobic Oxidative N-Heterocyclic Carbene Catalysis via Multistep Electron Transfer and its Application

    Författare :Anton Axelsson; Chalmers tekniska högskola; []
    Nyckelord :NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; NATURVETENSKAP; NATURAL SCIENCES; dihydropyranone; Michael addition; kinetics.; aerobic oxidation; acylation; N-heterocyclic carbene; green chemistry; Organocatalysis; electron transfer mediator; asymmetric synthesis;

    Sammanfattning : Oxidation reactions are ubiquitous in synthetic chemistry, but generally suffer from formation of large amounts of potentially toxic byproducts. Aerial oxygen represents an ideal oxidant since it is inexpensive, non-toxic and only forms water as a byproduct. LÄS MER

  7. 5. Regioselective acylation of carbohydrates and polyester synthesis by lipase catalysis

    Författare :Armando Córdova; KTH; []
    Nyckelord :;

    Sammanfattning : The lipases' high regio- and enantioselectivity, activity inorganic solvent and environmentally compatible reactionconditions have made lipase-catalysis based synthesis anattractive alternative to conventional synthetic methods inorganic chernistry and a new synthetic tool in polymerchemistry.The regioselective acylation of methy1 glycopyranosides wereinvestigated using several serine hydrolases.
