The methods comprise contacting at least a portion of the urine sample with a test strip comprising a reagent pad and detecting whether ascorbic acid is present in the urine sample. The detecting comprises measuring an intensity of color on the reagent pad, wherein a reduction in the intensity...
THERE has lately been some discussion about the state in which ascorbic acid is present in natural food materials. Ahmad, and McHenry and Grahamobserved that several fresh food-stuffs like cabbage, cauliflower, carrots, etc., give a higher ascorbic acid value on being cooked or boiled with ...
10.2 Ascorbic Acid Ascorbic acid is one of the most common interfering substances that affects the accuracy of glucose biosensors [72,73], especially for glucose biosensors based on electrochemical analysis. Ascorbic acid is oxidized at the electrode surface, thus resulting in the production of more...
a两个PO数量相同 Two PO quantities are same[translate] aascorbic acid, an antioxidant vitamin, may be present in Galician seaweeds intended for human consumption 抗坏血酸,抗氧化维生素,也许是存在打算的加利西亚海草供给人的消耗量[translate]
It would decompose when it melts. Specific optical rotation: +20.5 to +21.5°. Ascorbic acid is two-base acid (the pKa is 4.1 and 11.8). It occurs mainly in the form of sodium salt and calcium salt, and its aqueous solution is strongly acidic reaction. Ascorbic acid is a strong reducin...
Ascorbic acid (ascorbate/AsA/vitamin C) is one of the most abundant and versatile biomolecules in plants and animals. In particular, AsA is present in high concentrations in the chloroplasts and cytosol of plant species. In plants, AsA serves as a major antioxidant and enzyme cofactor and regul...
8.First, Asc is oxidized to DHAsc by oxygen present in the dough.第一,在面团中氧气的存在条件下将抗坏血酸氧化成脱氢抗坏血酸。 9.The reaction orders with respect to both Fe(Ⅲ)P and ascorbic acid are unit,and the reaction rate is influenced by the ascorbic acid dissociation.反应速率对铁...
Ascorbic acid (AA) is a powerful antioxidant required for the defense against oxidative stress. At present it is not known whether AA may play a role in the developmental process of the fetus. We therefore determined the relationship of AA levels between the umbilical cord vein (UCV) and umbi...
The method is considered to be having a good selectivity for the determination of ascorbic acid present in the samples of various fruits, commercial juices and sprouted food grains since some common ascorbic acid associated agents are not interfering in the determination of ascorbic acid, however, ...
Ascorbic acid (AA) is purported to have a preventative role in coronary heart disease (CHD) incidence. Studies in animal models support an interaction of AA in lipid metabolism, while results from epidemiological and supplementation trials conducted in humans are inconsistent. However, AA may mediate...
