Circular dichroism and ultraviolet spectroscopyof complexes of amylose

The circular dichroism of the complexes formed between slightly hydroxypropylated amylose and cyclomalto-hexaose, -heptaose, and -octaose ( α-, β-, and γ-cyclodextrin) with nine different achiral ketones and phenolphthalein has been investigated. In the complexes with the ketones, the amylose helix...

Description
Summary:The circular dichroism of the complexes formed between slightly hydroxypropylated amylose and cyclomalto-hexaose, -heptaose, and -octaose ( α-, β-, and γ-cyclodextrin) with nine different achiral ketones and phenolphthalein has been investigated. In the complexes with the ketones, the amylose helix has a conformation with six glucose units per turn, whereas, in the complex with phenolphthalein, it has seven.
