| 摘 要： | 果聚糖是高等植物重要的贮藏碳水化合物，因植物种类和发育阶段而异，主要存在5种类型的结构：线型菊糖型果聚糖、菊糖型果聚糖新生系列、线型梯牧草糖型果聚糖、混合型梯牧草糖型果聚糖和梯牧草糖型果聚糖新生系列。果聚糖的代谢模型随着代谢酶—蔗糖：蔗糖果糖基转移酶、蔗糖：果聚糖_6_果糖基转移酶、果聚糖：果聚糖果糖基转移酶、果聚糖：果聚糖_6_果糖基转移酶、果聚糖外水解酶等的发现、纯化和克隆日趋清晰。此外，果聚糖分子生物学研究也取得了一定的进展。

| Abstract: | About 15% of the flowering plant species store fructans, frucose_based carbohydrates. With different DP (degree of polymerization), five major classes of fructans —— linear inulin, inulin neoseries, linear levans, levans neoseries and mixed levans —— have been distinguished in higher plants. So far three models of fructan biosynthesis have been elucidated and structurally different fructan molecules can be produced by the concerted action of different fructosyltransferase. Recently the genes encoding these fructosyl_transferases have been cloned, opening new biotechnological opportunities for the use of fructans. |
