Descripción general

α-1,4-glucan with α-1,6-cross-linking; one terminal group per 25 glucose units

Aplicación

Amylopectin is a glucose-based, highly-branched polysaccharide which together with amylose makes starch. The glucosidic bonds of amylopectin are α-1,4 in the glucan chain and α-1,6 at the branch points. Amylopectin from maize differs in structure form amylopectin from other plant species and is used in the study of the development of starches.

Questions

1–2 of 2 Questions  
  1. I want to know how many monomers compose one polymer in average.

    1 answer
    1. Unfortunately, the average molecular weight of this product is not determined, therefore the number of monomeric subunits comprising the polymer cannot be estimated.

      Helpful?

  2. what is the molecular weight of amylopectin from maize?

    1 answer
    1. The molecular weight of this product has not been determined. However, a number of references suggest a molecular weight of 828.7.
