- W2065269078 abstract "Waxy maize starch (WMS) has been examined by electron microscopy to learn details of the structure of the molecules and their organization in starch granules. After dispersion in dimethyl sulfoxide WMS shows highly elongated irregular particles (molecules and aggregates) approximately 100 Å in diameter and several hundred angstroms long. Granules that have been mashed in water retain vestiges of granule organization, including “growth rings” and, after negative staining, show “rippled” fibrous structures, the ripples being about 70 Å apart along the fiber dimension. Thin (∼ 500-) sections of native granules show no interpretable detail, but after extensive acid treatment, the growth rings become very obvious and are composed of lamellae, about 50 Å thick, oriented in an irregular pattern, more or less tangential to the growth rings. Recrystallized Naegeli amylodextrin from WMS also shows platelets about 55 Å thick and several hundred angstroms in the other dimensions. We interpret the 70- ripples in the granule fragments as being alternations between amorphous and crystalline regions, the crystalline regions being due to the side-by-side association of parallel clusters of starch chains. During acid treatment, the more amorphous or gel phase of the granule gradually is eroded, the intercluster zones are hydrolyzed, and the more regular chains form crystalline lamellae. The thickness of one lamella is just the average length of a single 12- to 15-glucose unit molecular chain; that is, about 50 . We envision the molecular chains as being packed in double helices as is appropriate for the A-type Xray diffraction pattern, both before and after the acid treatment." @default.
