ascorbic acid, lanthanum, solutions, chelation, chelates, spectral analysis, aluminum, metal ions, lead, interactionsSpectroscopic evidence suggested that in aqueous solution, metal chelation can occur through ascorbate anion O-3 and O-2 atoms, whereas in the solid state metal coordination is through...
Likewise, Bt and Ht have significantly reduced edema in the paws of mice after carrageenan injection. These results suggested that the Luobuma teas polysaccharides can be explored as potential antioxidants and anti-inflammatory agents. select article The effect of the interactions of water activity, ...
Ascorbic acid was used as a positive control. SOD activity was estimated according to the formula described by Park et al. [15]. All analyses were performed using three biological replicates. Reducing power assay The reducing power of the methanol extracts of pak choi cultivars was evaluated as...
Ag+-3,3′,5,5′-tetramethylbenzidine as a probe for colorimetric detection of ascorbic acid in beverages Shu, XinChen, YongrenYuan, ChunlingWang, Yilin 1772-1776 Fabrication of liquid-liquid self-assembled Ag arrays on disposable screen-printed electrodes and their application in the identification...
Insights into metal–matrix interactions in atomically dispersed catalytic systems are necessary to exploit the true catalytic activity of isolated metal atoms. Distinct from catalytic atoms spatially separated but immobile in a solid matrix, here we demonstrate that a trace amount of platinum naturally ...
The scientific study of matter's characteristics and behaviour is known as chemistry.andare different from the normal vocabulary. It is a branch of natural science that examines the building blocks of matter, including the atoms, molecules, and ions that make up compounds and their composition, ...
Their morphology-dependent electrochemical activities were evaluated, and the conical NFs, with their higher density of exposed edge planes or free graphene-sheet ends, exhibit better electrochemical performance, which allows sensitive analysis of uric acid (UA) in the presence of ascorbic acid (AA; ...
The current challenge for the synthesis of such materials is to functionalize their nano-sized cavities; so that they can be well suited for specific host-guest interactions and practical applications. Our goals here are to develop synthetic approaches to address the challenge by the emerging ...
MH-OJMB presented a lower browning index and higher levels of ascorbic acid, total phenolics, and carotenoids, higher antioxidant activity, and greater α-amylase, α-glucosidase, and ACE inhibitory activity than the pasteurized product, similar to the untreated beverage. No significant differences ...
Following the hypothesis of the suggested link between microbial colonization patterns and the environmental conditions in vineyards, biodiversity studies have attempted to widely characterize the native microflora in diverse agricultural ecosystems aiming to perceive the dynamic interactions between plant, soil...
