   Keywords : wheat bran; corn bran; hemicellulose; arabinoxylan; ferulic acid; subcritical water extraction; acetylation; films; hydrogels; crosslinking; regeneration; antioxidant activity; vetekli; majskli; hemicellulosa; arabinoxylan; ferulsyra; subkritisk vattenextraktion; acetylering; filmer; hydrogeler; tvärbindning; regeneration; antioxidant aktivitet; Bioteknologi; Biotechnology;

   Abstract : Cereal production generates large quantities of by-products every year, which still remain underutilized. The hemicellulose fractions from cereal by-products are anticipated to play an important role in tomorrow's sustainable and bio-based circular economy. READ MORE

4. 2. Alpha-1-microglobulin, heme-binding protein, reductase and antioxidant

   Author : Maria Allhorn; Infektionsmedicin; []
   Keywords : MEDICIN OCH HÄLSOVETENSKAP; MEDICAL AND HEALTH SCIENCES; reduction; inflammation; chronic ulcers; collagen; low density lipoproteins; Medicin människa och djur ; Medicine human and vertebrates ; antioxidation; heme; hemoglobin; alpha-1-microglobulin; lipocalin;

   Abstract : This thesis describes structural and functional studies of alpha-1-microglobulin (a1m), a 26 kDa plasma and tissue protein that is evolutionarily well-conserved and belongs to the lipocalin superfamily. The lipocalins are polypeptides of 160-190-amino acids that are folded into an 8-stranded beta-barrel forming a pocket with a hydrophobic interior. READ MORE

5. 3. Selenium Compounds in Milk. Studies of Selenoproteins, Selenium Enrichment and Oxidative Stability of Food

   Author : Tien Hoac; Tillämpad biokemi; []
   Keywords : NATURVETENSKAP; NATURAL SCIENCES; metabolism; Biokemi; Metabolism; Biochemistry; Naturvetenskap; Natural science; Copper; Zinc; Oxidative stability; Thioredoxin reductase; Glutathione peroxidase; Selenoproteins; Milk; Selenium supplementation; Technological sciences; Teknik;

   Abstract : Selenium is an essential nutrient and in animals and humans it can either be specifically incorporated into proteins as selenocysteine or randomly as selenomethionine. It can also occur as low-molecular-weight compounds and the form of selenium in foods may also influence food quality. READ MORE

6. 4. Valorization of Kraft Lignin by Fractionation and Chemical Modifications for Different Applications

   Author : Selda Aminzadeh; Mikael Lindström; Hasan Jameel; KTH; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; Lignin Valorization- LignoBoost Lignin-Clean Flow Black Lignin- Characterization-Chemical modifications-Fractionation-applications; Chemical Engineering; Kemiteknik;

   Abstract : AbstractLignin is one of the most abundant biopolymers. Approximately 70 million tons of technical lignin is generated annually, but only little is used for products other than energy. The complexity of lignin hinders full utilization in high-value products and materials. READ MORE

7. 5. Protection of Biomolecules by Antioxidants - Mechanisms and Applications

   Author : Carl Grey; Bioteknik; []
   Keywords : TEKNIK OCH TEKNOLOGIER; ENGINEERING AND TECHNOLOGY; dG; antioxidants; mass spectrometry; Analytical chemistry; Analytisk kemi; Food and drink technology; Livsmedelsteknik; Bioteknik; Biotechnology; DNA; Oxidation; Protein; Fenton reaction;

   Abstract : Reactive oxygen species (ROS) consisting of various oxygen-based free radicals as well as other reactive non-radical species produced in O2-related metabolism or through other processes are involved in the oxidation of such vital biomolecules as DNA, proteins and lipids. The types of oxidation represented here are known to cause many different diseases and disorders in human beings, such as cancer, Alzheimer's disease and ageing. READ MORE
