Differential sensing of sugars by colorimetric arrays.
While the complexes between boronic acids and diols have been studied for decades, researchers continue to design new and interesting methods to use these interactions to produce saccharide sensors that are more sensitive and selective. Herein we discuss how the use of pattern-based colorimetric arrays from a collection of crossreactive sensors have been developed as new differential sensing pl...
متن کاملSome applications and limitations of the enzymic, reducing (Somogyi), and anthrone methods for estimating sugars.
The colorimetric glucose-oxidase and the Somogyi-Nelson reducing-sugar methods yield the same blood-glucose values when applied to carefully prepared zinc hydroxide filtrates of blood obtained from fasting individuals. The anthrone method yields values only slightly higher than those obtained by the enzymic and the reducing-sugar methods. Use of the enzymic method in conjunction with the reduci...
متن کاملThe direct colorimetric estimation of reducing sugars and other reducing substances with tetrazolium salts.
Since Kuhn & Jerchel (1941) showed that tetrazolium salts were reduced by bacteria, yeasts and germinating seeds, 2:3:5-triphenyltetrazolium chloride or bromide has come into prominence as a viability testing reagent (Cottrell, 1947) and for vital staining (Mattson, Jensen & Dutcher, 1947). Its specific advantages for this purpose and for the purposes which follow lie in its Eo value of -008 V....
متن کاملDifferences in Modified Morgan Phosphorus Levels Determined by Colorimetric and Inductively Coupled Plasma Methods
Phosphorus (P) fertilization is frequently needed for profitable crop production. Modified Morgan P (MMP) is a soil test P used to estimate plant available P in soils. The critical values of MMP for P fertilization and maintenance recommendations are based on the P concentrations measured by a common colorimetric molybdenum blue method although other P quantification methods have also been used...
متن کاملColorimetric Method for Determination of Sugars and Related Substances
Simple sugars, oligosaccharides, polysaccharides, and their derivatives, including the methyl ethers with free or potentially free reducing groups, give an orangeyellow color w-hen treated with phenol and concentrated sulfuric acid. The reaction is sensitive and the color is stable. By use of this phenol-sulfuric acid reaction, a method has been developed to determine submicro amounts of sugars...
