項目摘要

穀物澱粉是微米尺度的多糖聚合體，分子量巨大、構型複雜，澱粉整體的晶體學結構目前未解。本課組在前期研究中發現穀物澱粉存在納米尺度的中間體，在研究澱粉中間體分子量的MALDI－TOF質譜測定中，又發現各種多糖峰以常態分配組合、分子量呈現有序排列，顯示出多糖片段和封閉結構的有序規律。本課題針對中間體MALDI－TOF質譜實驗顯示出多糖組成的有序規律，引進同步輻射的X射線衍射和小角X射線散射實驗技術，分析、測定玉米澱粉中間體的多糖直鏈片段和封閉結構等有序組成規律與晶體結構之間的關係；使同步輻射的X光束線站在解決澱粉中間體、多糖聚合問題中的套用打開突破口，使澱粉晶體學研究獲得新的認知和進展；在其他分析方法的配合下，為優異穀物種質的性狀、專用食品原料，提供納米尺度的數據和指標；為保障食品質量和安全、指導有效使用糧食資源，提供參考依據和實驗技術。
