title: New alpha-amylase inhibitor, trestatins. II. Structure determination of trestatins A, B and C.
abstract: The structures of trestatins A (C56H94N2O40), B (C37H63NO28) and C (C75H125N3O52), new basic oligosaccharides with potent inhibitory activity against various alpha-amylases, have been shown by spectroscopic and chemical methods to be 1, 2 and 3, respectively.
