The sulfolipid sulfoquinovosyl diacylglycerol (SQDG) and its headgroup, the sulfosugar sulfoquinovose (SQ), are estimated to harbour up to half of all organosulfur in the biosphere. SQ is liberated from SQDG and related glycosides by the action of sulfoquinovosidases (SQases). We report a 10-step synthesis of SQDG that we apply to the preparation of saturated and unsaturated lipoforms. We also report an expeditious synthesis of SQ and (13C6)SQ, and X-ray crystal structures of sodium and potassium salts of SQ. Finally, we report the synthesis of a fluorogenic SQase substrate, methylumbelliferyl α-d-sulfoquinovoside, and examination of its cleavage kinetics by two recombinant SQases. These compounds will assist in dissecting the role of sulfoglycolysis in the biogeochemical sulfur cycle and understanding the molecular basis of sulfoglycolysis.

In this study, from the solid-liquid phase diagrams for 19 binary mixtures of tetrabutylammonium carboxylate-water, the effect of the shape and/or length of the alkyl group of a carboxylate anion on the stability (i. e. , melting point) and the crystal structure (i. e. , hydration number) of their clathrate hydrates has been systematically examined. These fundamental data would also offer a guiding principle, for example, for highly selective separation of a specific carboxylate anion from an aqueous solution containing several kinds of carboxylate anions by means of the formation of a mixed clathrate hydrate of tetrabutylammonium carboxylates.
