xylose

 [zi´lōs]
a pentose found in mucopolysaccharides of connective tissue, sometimes the urine, and vegetable gum. d-Xylose is used in a diagnostic test of intestinal absorption (see malabsorption syndrome).

xy·lose (Xy, Xyl),

(zī'lōs),
An aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of naturally occurring carbohydrate substances, for example, in wood fiber. An important dietary component for herbivores. The d-isomer is also known as wood or beechwood sugar.

xylose

/xy·lose/ (zi´lōs) a pentose found in plants in the form of xylans; it is used in a diagnostic test of intestinal absorption.

xylose

(zī′lōs′)
n.
A crystalline monosaccharide, C5H10O5, that is a component of most hemicelluloses in plants. Also called wood sugar.

xylose

[zī′lōs]
an aldopentose sugar produced by hydrolyzing straw and corn cobs. It is incompletely absorbed when taken by mouth and is used in diagnostic studies of the digestive tract.

xy·lose

(zī'lōs)
An aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of carbohydrate.

xylose

a PENTOSE SUGAR that is present in plant cell walls. Formula: C5 H10 O5.

xy·lose

(zī'lōs)
An aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of carbohydrate.

xylose (zī´lōs´),

n wood or beechwood sugar; an aldopentose, isomeric with ribose, obtained by fermentation or hydrolysis of naturally occurring carbohydrate substances such as wood fiber.

xylose

a pentose occurring in mucopolysaccharides of connective tissue and sometimes in the urine; also obtained from vegetable gum.

xylose absorption test, d-xylose absorption test
d-xylose absorbed primarily in the duodenum and cranial jejunum; after oral administration, urine or plasma determination at timed intervals can be used as an indication of intestinal absorption.
