A 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...
متن کاملSemi-micro Estimation of Reducing Sugars.
The estimation of sugars is a matter of interest to every worker engaged in the study of carbohydrate metabolism and related problems. In order to be of any real value a method must not only allow the determination of relatively small amounts of sugars with sufficient accuracy, but should also be rapid, and thus permit of a large number of determinations being carried out in a short time. Semi-...
متن کاملinvestigating the feasibility of a proposed model for geometric design of deployable arch structures
deployable scissor type structures are composed of the so-called scissor-like elements (sles), which are connected to each other at an intermediate point through a pivotal connection and allow them to be folded into a compact bundle for storage or transport. several sles are connected to each other in order to form units with regular polygonal plan views. the sides and radii of the polygons are...
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 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....
