Gulose aqueous solution

Preparation. D-Gulose may be obtained as a pure syrup by the Kiliani synthesis from D-xylose.111 Crystalline a-D-gulose.CaCl2.H2O was obtained upon evaporating in vacuo an aqueous solution of D-gulose containing about two molecular equivalents of calcium chloride.112... [Pg.25]

For the same conformational reasons, the P anomers of d aldoses dominate in aqueous solution when the Cf atom has the D configuration (ribose, xylose, allose, glucose, gulose, galactose). The a anomers, however, predominate when the atom has the l configuration (arabinose, lyxose, altrose, mannose, idose, talose). [Pg.566]

By treatment of D-gulose (XVII) or D-idose (XVIII) with warm aqueous barium hydroxide solution Van Ekenstein and Blanksma were able to isolate D-sorbose (II) with a melting point of 165° and [< ]d + 42.9° in water. The aldoses were prepared from D-gulonic and D-idonic lactones obtained by the cyanohydrin synthesis from D-xylose. [Pg.106]
