摘要：

Electron microscopy rapidly destroys organic structures such as starch granules. Because of this, the structure of starch is still controversial. But a new X-ray diffraction experiment has used an exceptionally narrow bean to scan across single granules of starch, showing that they are ellipsoids made of alternating crystalline and amorphous layers. One eventual application of these studies may be the use of starch as a biodegradable plastic.
