Molecular structure of an hypothetical xylooligosaccharide, where n is a variable number of xylose units such as xylobiose and xylotriose. Xylooligosaccharides (XOS) are polymers of the sugar xylose. [1]
Various types of potatoes Unprocessed seeds of spelt, a historically important staple food Harvesting Sago pith to produce the starch in Papua New Guinea. A staple food, food staple, or simply staple, is a food that is eaten often and in such quantities that it constitutes a dominant portion of a standard diet for an individual or a population group, supplying a large fraction of energy needs ...
Steroid glycosides are saponins with 27-C atoms. [4] They are modified triterpenoids where their aglycone is a steroid, these compounds typically consist of a steroid aglycone attached to one or more sugar molecules, which can have various biological activities.
Carbohydrates (literally hydrates of carbon) are chemical compounds, which together with proteins, lipids , and nucleic acids (RNA/DNA), constitute the 4 principal biological macromolecules of which all life on Earth is composed. Together with lipids, carbohydrates are the primary means by which living organisms store energy.
Generally, the carbohydrate part(s) play an integral role in the function of a glycoconjugate; prominent examples of this are neural cell adhesion molecule (NCAM) and blood proteins where fine details in the carbohydrate structure determine cell binding (or not) or lifetime in circulation.

The specific carbohydrate diet (SCD) is a restrictive diet originally created to manage celiac disease; it limits the use of complex carbohydrates (disaccharides and polysaccharides). Monosaccharides are allowed, and various foods including fish, aged cheese and honey are included.
Molisch test (using α-napthol) indicating a positive result (see purple ring). Molisch's test is a sensitive chemical test, named after Austrian botanist Hans Molisch, for the presence of carbohydrates, based on the dehydration of the carbohydrate by sulfuric acid or hydrochloric acid to produce an aldehyde, which condenses with two molecules of a phenol (usually α-naphthol, though other ...
