The Effects of Enzymes, Species, and Storage of Raw Material on Physicochemical Properties of Protein Hydrolysates from Whitefish Heads

open access: yesMarine Drugs, 2023
The rest raw materials of whitefish have great potential for increased utilisation and value creation. Whitefish heads have a high protein content and should be considered a healthy protein source for the growing population’s demands for sustainable ...

Molecular Weight Distribution of Proteins [PDF]

open access: yesNature, 1946
THE recent publication1 of an examination of Svedberg's theory of molecular weight distribution, in which the theory is considered to be invalid, suggests that a treatment, similar in some of its details, might be of interest. This was prepared in 19442, and the conclusions agree with those of Johnston, Longuet-Higgins and Ogston1, and with those of ...

The molecular weight (MW) and molecular weight distribution (MWD) of NR from different age and clone Hevea trees [PDF]

open access: yesSongklanakarin Journal of Science and Technology (SJST), 2005
NR-latex was tapped from different age and clone Hevea trees. The latex of virgin started from 3 years trees was transesterified to reduce the branching molecules. The molecular weight (MW) and molecular weight distribution (MWD) of rubber molecules were

Effect of different ligands on the controlled polymerization of monodisperse polystyrene nanospheres by atom transfer radical polymerization in an aqueous emulsion

open access: yeseXPRESS Polymer Letters, 2012
Polystyrene nanospheres have been synthesized by atom transfer radical polymerization (ATRP) to control the molecular weight distribution in the aqueous system. The crucial factor in such a system is the ligand that adjusts the solubility of the catalyst

SEC2MWD: A MATLAB toolbox for derivation of molecular weight distributions from size exclusion chromatography

open access: yesSoftwareX
Size exclusion chromatography (SEC) is a type of liquid chromatography used for separating molecules based on their size. The pipeline for converting a raw chromatogram to a molecular weight distribution involves multiple steps and require various ...

Controlled depolymerisation, as assessed by analytical ultracentrifugation, of low molecular weight chitosan for potential use in archaeological conservation [PDF]

open access: yes, 2018
The heterogeneity and molecular weight of a chitosan of low molecular weight (molar mass) and low degree of acetylation (0.1), for potential use as a consolidant for decayed archaeological wood, has been examined by sedimentation velocity and ...

Employing Moment Equations Model to Study the Effect of Different Active Centers on Homopolymerization Kinetics of Ethylene [PDF]

open access: yesعلوم و تکنولوژی پلیمر, 2008
Ethylene was homopolymerized over Ziegler-Natta catalyst and the homopolymerization was modeled using moment equations. Mechanism was modeled according to five different reaction centers of catalyst.

Modeling Maintenance of Long-Term Potentiation in Clustered Synapses, Long-Term Memory Without Bistability [PDF]

open access: yes, 2015
Memories are stored, at least partly, as patterns of strong synapses. Given molecular turnover, how can synapses maintain strong for the years that memories can persist?
