Comparison of apple polyphenol-gelatin binary complex and apple polyphenol-gelatin-pectin ternary complex: Antioxidant and structural characterization

, 2021
Polyphenol-gelatin binary complex and polyphenol-gelatin-pectin ternary complex were synthesized. The differences in antioxidant activity between the binary complex and ternary complex were evaluated by using ABTS, DPPH, and reducing power assays.

The Structural Characterization of Amavadin

Angewandte Chemie International Edition, 1999
Fly agaric accumulate vanadium in the form of amavadin, whose structure has been elucidated (see picture for the crystal structure). Amavadin contains one VIV center coordinated to two (S,S)-hidpa3- ligands (H3 hidpa=2,2'-(hydroxyimino)dipropionic acid) through one η2 -NO- group and two unidentate carboxylato groups from each ligand. The arrangement of

Structural characterization of glycoproteins

Journal of Chromatography A, 1988
The structural characterization of glycoproteins by high-performance liquid chromatography (HPLC) is often difficult because of microheterogeneity of their oligosaccharide groups. To investigate this phenomenon, a series of human plasma glycoproteins of known amino acid sequence and carbohydrate structure was subjected to comparative study by HPLC ...

Lignin Source and Structural Characterization.

ChemSusChem, 2020
Lignin is a primary component of lignocellulosic biomass and an underutilized feedstock in the growing pulping and biofuel industries. Currently, over 50 million tons of industrial lignin are produced annually from pulping and bioethanol processes in the

Characterization of MagFET structures

2008 15th IEEE International Conference on Electronics, Circuits and Systems, 2008
The paper deals with characterization of various MagFET structures in alternating magnetic field in frequency range from 10 Hz to 10 kHz. 3D numerical simulation of MagFET structures has been used to investigate influence of MagFET geometry to the magnetic field sensitivity.

Structural characterization and immune enhancement activity of a novel polysaccharide from Moringa oleifera leaves.

Carbohydrate Polymers, 2020
A novel polysaccharide, designated as MOP-3, was extracted and isolated from the leaves of Moringa oleifera. Structural characterization showed that MOP-3 had a molecular weight (MW) of 4.033 × 106 Da and was composed of arabinose, glucose and galactose ...

An Exact Characterization of Greedy Structures

SIAM Journal on Discrete Mathematics, 1993
Summary: The authors present exact characterizations of structures on which the greedy algorithm produces optimal solutions. Our characterization, which are called matroid embeddings, complete the partial characterizations of \textit{R. Rado} [Note on independent functions, Proc. London Math. Soc., III.

Structural and Thermodynamic Characterization of Polyphenylbenzenes

The Journal of Physical Chemistry A, 2011
The thermodynamic and structural study of a series of polyphenylbenzenes, from benzene, n(Ph) = 0, to hexaphenylbenzene, n(Ph) = 6, is presented. The available literature data for this group of compounds was extended by the determination of the relevant thermodynamic properties for 1,2,4-triphenylbenzene, 1,2,4,5-tetraphenylbenzene, and ...
