Indican

Definitions

  • Webster's Revised Unabridged Dictionary
    • Indican (Chem) A glucoside (C14H17NO6) obtained from woad (indigo plant, Isatis Tinctoria) and other plants (see indigo), as a yellow or light brown sirup. When purified it is obtained as spear-shaped crystals. It has a nauseous bitter taste. By the action of acids, enzymes, etc., it breaks down into sugar and indigo. It is the source of natural indigo. Chemically it is the 3-glucoside of indole, H-indol-3-yl-β-D-glucopyranoside.
    • Indican (Physiol. Chem) An indigo-forming substance, found in urine, and other animal fluids, and convertible into red and blue indigo (urrhodin and uroglaucin). Chemically, it is indoxyl sulphate of potash, C8H6NSO4K, and is derived from the indol formed in the alimentary canal. Called also uroxanthin.

Century Dictionary and Cyclopedia
    • n indican The natural glucoside (C26H31NO17) by the decomposition of which indigo blue is produced from the various species of indigo-producing plants. It forms a transparent brown syrup, the aqueous solution of which has a yellow color, bitter taste, and slightly acid reaction. By the action of dilute mineral acids it splits up, forming indigo blue, indigo red, and indiglucin.
    • n indican The alkali salt of indoxyl-sulphuric acid, C8H6NSO4H. It occurs in urine. See the following phrase.

La segunda fase ocurre para z ≪ zeq , en el cual es universo es dominado por materia, que en los casos más sencillos se comporta como un modelo de Einstein-de Sitter; (c) Observaciones de supernovas indican que actualmente existe una dominación de constante cosmológica sobre los otros tipos de materia.
The quantum origins of the cosmological asymmetry
Observaciones (e.g. [148]) indican que las anisotropías se pueden modelar como un campo aleatorio gaussiano, i.e. , las variables aleatorias del campo aleatorio tienen una distribución de probabilidad gaussiana.
