title: The conformation of alpha-(1-->4)-linked glucose oligomers from maltose to maltoheptaose and short-chain amylose in solution.
abstract: The conformation of maltose-type oligomers in water and in dimethylsulfoxide (Me2SO) was studied using two-dimensional NMR spectra. In Me2SO all of the oligomers have a 1a-type conformation. In water, they tend to adopt the same conformation, but the oligomers are looser and more flexible than in Me2SO.
