The structure of vaucheriaxanthin.
نویسنده
چکیده
Vaucheriaxanthin is 19'-OH and not 19-OH neoxanthin. This structural conclusion was borne out by mass, PMR and infrared (IR) spectra from the free pigment and its derivatives (vaucheriaxanthal, vaucheriaxanthal-diacetate, vaucheriaxanthal-diacetate-mono (trimethylsilyl) -ether, vaucheriaxanthintriacetateand triacetate-monosilanate, vaucheriaxanthin-dimethylether) and by comparison of the characteristic lines of epoxi-xanthophylls at m/e 181 and m/e 221 in the mass spectrum.

متن کاملHalf-metallic properties of KP compound in a bulk and (001) surface of rock-salt structure: A b-initio study
Given the many applications of half-metals in the spintronics devices, we investigated the half-metallic properties of the KP compound in rock-salt (RS) and cesium chloride (CsCl) structural phases by using density functional theory. The results indicated that the KP compound as the half-metal in the RS structure, in contrast to the CsCl structure, due to the small lattice constant and failure ...
