Journal ArticleDOI
Antioxidant properties of Chinese yellow wine, its concentrate and volatiles
TL;DR: In this paper, the antioxidant activity of YW and its concentrate and volatile compounds (VC) was determined in terms of total antioxidant, reducing capacity, free radical scavenging, metal chelating and superoxide anion scavenging activities.
Journal ArticleDOI
Carbohydrate physiology of mycorrhizal roots of beech. i. identity of endogenous sugars and utilization of exogenous sugars
D. H. Lewis,J. L. Harley +1 more
TL;DR: The presence of several classes of reducing substances in mycorrhizal roots of beech is demonstrated, throwing considerable doubt on the values of 'easily soluble reducing substances' which have been used for correlation with degree of mycor rhizal infection by several workers.
Journal ArticleDOI
Evaluation of free radical-scavenging properties of commercial grape phenol extracts by a fast colorimetric method
TL;DR: In this article, three commercial extracts of grape phenols (seeds, skin, whole) were used in a study, and each extract was divided by HPLC into five fractions of different polarities, and their free radical-scavenging activities were measured using the DPD (N, N -diethyl-p -phenylenediamine) colorimetric method.
Journal ArticleDOI
The transport and metabolism of (14)C-labelled indoleacetic acid in intact pea seedlings.
TL;DR: Together, the decarboxylation of IAA and the formation of IAAsp operated to maintain a relatively constant level of free IAA-14C in the root system.
Journal ArticleDOI
A nitrite reductase with cytochrome oxidase activity from Micrococcus denitrificans
Ying Lam,D.J.D. Nicholas +1 more
TL;DR: The physiological role of the cytochrome oxidase activity associated with the purified nitrite reductase is likely to be of secondary importance for the following reasons: (a) it accounts for less than 10% of total cy tochrome c oxid enzyme activity of cell extracts; (b) the constitutive cyto chrome c oxidase has a smaller Km for O2 and would therefore be expected to function more efficiently especially at low concentrations of O2.

Optical Rotatory Dispersion. Its Application to Protein Conformation.
E. F. Woods,Donnell +1 more
TL;DR: Optical rotation has been found to be one of the most convenient methods of following the denaturation of proteins and rotatory dispersion is capable of providing information on the folding of the polypeptide chain in proteins and the changes accompanying denaturation.
