Sensory and physicochemical properties of enzymatic protein hydrolysates : Influence of raw material, protease, and downstream processing
(Doctoral thesis, 2021-04-12)The world aquaculture, fisheries and poultry sectors generate large amounts of residual raw materials, such as heads, backbones, and carcasses. Almost 85% of the residual materials from Norwegian aquaculture and fisheries ... -
Serum fatty acid and lipoprotein subclass concentrations and their associations in prepubertal healthy Norwegian children
(Peer reviewed; Journal article, 2016-03)Introduction The lipid metabolism is one of the most important and complex processes in the body. Serum concentrations of 18 fatty acids (FAs) and 24 lipoprotein features, i.e. concentrations of lipoprotein main and ... -
Silica-supported Z-selective Ru olefin metathesis catalysts
(Peer reviewed; Journal article, 2020)Recently reported thiolate-coordinated ruthenium alkylidene complexes show promise in Z-selective and stereoretentive olefin metathesis reactions. Herein we describe the immobilization of three Ru complexes containing a ... -
Similarity-Based Methods and Machine Learning Approaches for Target Prediction in Early Drug Discovery: Performance and Scope
(Journal article; Peer reviewed, 2020-05)Computational methods for predicting the macromolecular targets of drugs and drug-like compounds have evolved as a key technology in drug discovery. However, the established validation protocols leave several key questions ... -
Skin Doctor: Machine learning models for skin sensitization prediction that provide estimates and indicators of prediction reliability
(Peer reviewed; Journal article, 2019-09-28)The ability to predict the skin sensitization potential of small organic molecules is of high importance to the development and safe application of cosmetics, drugs and pesticides. One of the most widely accepted methods ... -
