title: X-ray structure of a sodium salt of digeneaside isolated from red alga Ceramium botryocarpum.
abstract: X-ray diffraction analysis has been recently used to determine the crystal structure of the floridoside (2-O-alpha-d-galactopyranosylglycerol) isolated from red alga Palmaria palmata and Dilsea carnosa, respectively [Simon-Colin, C.; Michaud, F.; Léger, J.-M.; Deslandes, E. Carbohydr. Res.2003, 338, 2413-2416; Vonthron-Senechau, C.; Sopkova-de Oliveira Santos. J.; Mussio, I.; Rusig, A. M. Carbohydr. Res. 2008, 343, 2697-2698]. In this present study, a similar analysis was performed on another compound belonging to the glycopyranosyl-glycerols family present in red algae, digeneaside. The crystal structure of a hydrated sodium salt of digeneaside (sodium 2-O-alpha-d-mannopyranosyl-d-glycerate monohydrate) was determined by single-crystal X-ray diffraction analysis at 110+/-3K. The space group is C2 with Z=4, a=17.9315(12), b=6.2693(4), c=10.7805(7)A, beta=90.746(7) degrees .
