Starch identification

The, chain voAiantS are characterized by the presence of two abnormal components, an abnormal Hb-F (02 /2) and an abnormal Hb-A (tt2 32) Of these two, the 02 2 component dominates and the 02 32 component Is often difficult to detect. The methods of choice are starch gel electrophoresis and anion-exchange chromatography using DEAE-Sephadex or DE-52 Cellulose. Chain analyses of these Isolated hemoglobin components will lead to a definitive Identification. 

The identification of anionic polyfacrylic acid) sizes can be carried out by staining with a fluorescent cationic dye (Cl Basic Orange 14) followed by spectroscopic measurement of excitation wavelength and fluorescence emission [195,196]. Such methods can also be used (with Cl Basic Orange 14 or Cl Basic Red 1) to detect and estimate carboxymethylcellulose, poly(vinyl alcohol) and starch derivatives [197].

The dependence of the mobilities of amylopectin and amylose on iodine concentration in the background electrolyte and applied temperature was studied by Brewster et al. (111). The method was used for the separation and identification of different plant starches, but no binding constants were calculated.

An excellent alternative to the starch gel medium is cellulose acetate if gels are to be run in the field for species identification, population structure studies, or selection of individuals for particular marker alleles. As buffer systems are often specifically adapted to the gel medium used, we recommend consulting the manual by Richardson et al.3 for technical information on cellulose acetate electrophoresis. 

Identification Add 1 drop of starch TS and a few drops of 20% hypophosphorous acid to 5 mL of a saturated solution of sample. A transient blue color appears. 

Identification Cautiously pass a few milliliters of sample gas through 10 mL of 1 N sodium hydroxide that has previously been chilled in an ice bath. The resulting solution gives positive tests for Chloride, Appendix IIIA, and it darkens starch iodide paper. 

Identification Add 0.1 mL of iodine TS to a suspension of 1 g of sample in 10 mL of water, and shake the mixture for 30 s. The reagent is discolored (distinction from polyvinylpyrrolidone, which produces a red color). Add 1 mL of starch TS, and shake the mixture. No blue color appears.

Another method of identification of the gas is (iii) to hold a filter paper, moistened with potassium iodate and starch solution, in the vapour, when a blue colour, owing to the formation of iodine, is observable ... 

The requirement of chloroplast photosynthesis for Pj and the release of Pj by sucrose synthesis in the cytosol require that these two processes be closely coordinated. Part of this coordination, as explained above, lies in the characteristics of the triose phosphate translocator. Results obtained in the last few years have led to the identification of a second component serving this function. Fructose 2,6-bis-phosphate (Fru-2,6-P2) coordinates the metabolism of sucrose, starch and CO2 fixation and, in so doing, links metabolic processes of the chloroplast with those of the cytosol.
