NMR and circular dichroism (CD) comparison with synthetic L-L DKPs allowed us to determine unambiguously the L-L absolute configuration of the natural DKPs. This work initiated the setting up of an optical properties database of natural DKPs, including specific rotation and CD. specialized SUBSTANCE NATURELLE RECIF CORALLIEN INVERTEBRE AQUATIQUE EXTRACTION ANALYSE CHIMIQUE STRUCTURE CHIMIQUE SPECTROSCOPIE EPONGE MARINE FIDJI PACIFIQUE 035SUBSAN01 90 2 1351-1366 2015 0385-5414 https://www.documentation.ird.fr/hor/fdi:010063520 10.3987/COM-14-S(K)87 0385-5414 [F B010063520] https://www.documentation.ird.fr/hor/fdi:010063520 https://www.documentation.ird.fr/intranet/publi/depot/2015-02-09/010063520.pdf Accès réservé (Intranet de l'IRD) IRD - Base Horizon / Pleins textes 2015-02-09 2015-06-22 fdi:010063520 fre
