A new principle for macromolecular structure determination
Protein NMR spectroscopy is a modern experimental technique for elucidating the threedimensional structure of biological macromolecules in solution. From the data-analytical point of view, structure determination has always been considered an optimisation problem: much effort has been spent on the development of minimisation strategies; the underlying rationale, however, has not been revised. C...

various biological activities, such as antitumor, antimalarial, antifeedant, insecticidal, antiinflammatory, amoebicidal, and herbicidal effects. We are interested in such biologically active compounds and have isolated many quassinoids from plants, such as Brucea antidysenterica, Picrasma ailanthoides, and Brucea javanica. As part of these studies, we investigated the isolation of quassinoids ...
متن کاملTriterpenoid saponins from Gypsophila altissima L.
Two new triterpenoid saponins (1, 2) were isolated from the roots of Gypsophila altissima L. (Caryophyllaceae), together with a known compound (3). The structures of new saponins were established as quillaic acid 3-O-beta-D-xylopyranosyl-(1-->3)-beta-D-glucuronopyranoside (1), and 3-O-beta-D-galactopyranosyl-(1-->2)-[beta-D-xylopyranosyl-(1-->3)]-beta-D-glucuronopyranosyl quillaic acid 28-O-(6-...
متن کاملA revision of the “African Non-Spiny” Clade of Solanum L. (Solanum sections Afrosolanum Bitter, Benderianum Bitter, Lemurisolanum Bitter, Lyciosolanum Bitter, Macronesiotes Bitter, and Quadrangulare Bitter: Solanaceae)
The African Non-Spiny (ANS) clade contains 14 species of mostly large canopy lianas or scandent shrubs confined to Madagascar (10) and continental Africa (4, with with one species reaching the southern Arabian peninsula). Members of the clade were previously classified in sections Afrosolanum Bitter, Benderianum Bitter, Lemurisolanum Bitter, Macronesiotes Bitter and Quadrangulare Bitter, and we...
متن کاملBitter Peptides, Occurrence and Structure
The bitter taste of many protein rich foods resides in the peptide fraction. 61 bitter tasting peptides, isolated from natural systems, and 145 bitter tasting synthetic peptides are reviewed. The relationships between average hydrophobicity and bitter taste are then discussed.
