Abstract:

The present study was conducted in order to evaluate the starch components contained in several maize mutants. The α1,4‐α1,6 glucopolysaccharides were fractionated according to their branching degree. The determination of the wavelenght of maximum absorption (γ max) in the presence of Krisman's reagent [12] as well as the glucose α1,6 linkages involved in the branching point were determined. The mutants analyzed possess characteristics that allow us to identify them according to the composition and structural properties of their polysaccharides (phytoglycogen, amylopectin, amylose).
