Abstract

In this paper, we describe that amylose almost selectively includes poly(tetrahydrofuran) (PTHF) from a mixture of poly(oxetane) (POXT) and PTHF having resemblant chemical structures and molecular weights in vine-twining polymerization. This was performed by the phosphorylase-catalyzed enzymatic polymerization of alpha-D-glucose 1-phosphate from maltoheptaose as a primer in the presence of a mixture of POXT and PTHF to produce an amylose-PTHF inclusion complex.

摘要

在本文中，我们描述了在藤蔓缠绕聚合反应中，直链淀粉几乎能从具有相似化学结构和分子量的聚（氧杂环丁烷）（POXT）和聚（四氢呋喃）（PTHF）的混合物中选择性地包合聚（四氢呋喃）（PTHF）。这是通过在POXT和PTHF的混合物存在下，以麦芽七糖为引物，由磷酸化酶催化α-D-葡萄糖1-磷酸的酶促聚合反应来制备直链淀粉-PTHF包合物实现的。
