Carbohydrate Research, 2010 Amylopectin fine structures were studied following limited hydrolysis of gelatinised waxy maize starch by amylases with a different level of inner chain attack (LICA). This was done by size exclusion chromatography as well as by debranching the (partially hydrolysed) amylopectin samples and studying the size distributions of the released chains.

Structural Differences in Amylopectin Affect Waxy Rice Processing
Plant Production Science, 2002 We studied the varietal differences in the rice cake hardening rate, which is one of the important characters in waxy rice processing. Waxy upland rice cv.

Polymers, 2022 Amylopectin from waxy corn and the three nanosized amylopectin fragments (NAFs)—NAF(56), NAF(20), and NAF(8)—from waxy corn starch with a hydrodynamic diameter of 227, 56, 20, and 8 nm, respectively, were randomly labeled with 1-pyrenebutyric acid. The efficiency of these pyrene-labeled amylopectin-based polysaccharides (Py-AbPS) for pyrene excimer ...

The fine structure of amylopectin
Carbohydrate Research, 1981 Abstract A critical examination of an enzymic method for determining the ratio of A and B chains in amylopectin leads to a value of ∼ 1:1, and not 2:1 as suggested other workers. Partial debranching with pullulanase gave results consistent with earlier suggestions that A chains are predominantly and selectively removed. The ratio of A and B chains in

In Planta Expression of Thermophilic GtGBE Mimics BEIIb and Modifies Rice Starch Structure Without Yield Penalties. [PDF]
Plant Biotechnol JABSTRACT Enzymatic modification using glycosyltransferases offers a green route to produce highly branched starch to enhance starch functionality in the food industry, yet this approach faces challenges including the high cost of enzyme production and inefficiency.

Changes in fine structure of amylopectin and internal structures of starch granules in developing endosperms and culms caused by starch branching enzyme mutations of japonica rice [PDF]
, 2022 Cereals have three types of starch branching enzymes (BEs), BEI, BEIIa, and BEIIb. It is widely known that BEIIb is specifically expressed in the endosperm and plays a distinct role in the structure of amylopectin because in its absence the amylopectin ...
