Abstract
The amylose and amylopectin fractions from kernel starch synthesized shortly after exposure of intact Zea mays L. plants to (14)CO(2) had similar specific radioactivities (counts per min per mg of carbohydrate). In both fractions the radioactivity was distributed throughout the molecules. These data are consistent with a model in which the polysaccharides are synthesized in the matrix of the amyloplast followed by crystallization of the completed molecules onto the starch granule.
摘要
用 (14)CO(2) 处理完整的玉米植株后不久合成的玉米胚乳淀粉中的直链淀粉和支链淀粉的分数具有相似的比放射性（每分钟每毫克碳水化合物的计数）。在这两个分数中，放射性物质分布在整个分子中。这些数据与一个模型一致，即多糖在质体基质中合成，然后完整的分子结晶到淀粉颗粒上。
