The Determination of Reducing Sugars
In the course of an investigation, still in progress, of the physiological activity of a group of soil organisms, it became necessary to determine the quantity of dextrose in a series of solutions. It was desirable to have a method as accurate as the Fehling gravimetric one but which would yield results about as quickly as by direct titration. The reducing sugar present in the 150 cc. of each o...
متن کاملE Analytical Determination of Reducing Sugars
There have been very many methods suggested from time to time for the determination of reducing sugars, and considerable difficulty has been experienced in obtaining one which is sufficiently foolqxoof to give satisfactory results in the hands of all operators. In 1936 von Stieglitz and Home 11) reviewed several methods and recommended the electro* metric determmat~on of the end point with the ...
متن کاملThe determination of reducing sugars by titration of ferricyanide.
THE use of ferricyanide for the quantitative estimation of sugar was introduced by Hagedorn and Jensen [1923]. Their method has been extended to other sugars by Hanes [1929] and Hulme and Narain [1931]. These methods involve a preliminary heating for 15 minutes and a subsequent back titration. The fact that ferricyanide is only slightly coloured would seem to make it valueless for a direct titr...
متن کاملA Semi-micro Method for the Determination of Reducing Sugars.
The MUNSON-WALKER method (3) with the modification of BERTRAND (1) has long been used for the determination of reducing sugars in plant extracts. The large amiiounts of solutions required by this method, however, make necessary the frequent preparation and standardization of solutions, which is inconvenient when large numbers of determinations are being made over an extended period of time. For...
