  2. Monosaccharide - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide

    The table sugar used in everyday vernacular is itself a disaccharide sucrose comprising one molecule of each of the two monosaccharides D-glucose and D-fructose. [ 2 ] Each carbon atom that supports a hydroxyl group is chiral , except those at the end of the chain.

  3. L-Glucose - Wikipedia

    en.wikipedia.org/wiki/L-Glucose

    l-Glucose is an organic compound with formula C 6 H 12 O 6 or O=CH[CH(OH)] 5 H, specifically one of the aldohexose monosaccharides. As the l-isomer of glucose, it is the enantiomer of the more common d-glucose. l-Glucose does not occur naturally in living organisms, but can be synthesized in the laboratory.

  4. Glucose - Wikipedia

    en.wikipedia.org/wiki/Glucose

    Glucose circulates in the blood of animals as blood sugar. [6] [8] The naturally occurring form is d-glucose, while its stereoisomer l-glucose is produced synthetically in comparatively small amounts and is less biologically active. [8] Glucose is a monosaccharide containing six carbon atoms and an aldehyde group, and is therefore an aldohexose ...

  5. Monosaccharide nomenclature - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide_nomenclature

    Another nomenclature uses the systematic name of the molecular graph, a ' D-' or ' L-' prefix to indicate the position of the last chiral hydroxyl on the Fischer diagram (as above), and another italic prefix to indicate the positions of the remaining hydroxyls relative to the first one, read from bottom to top in the diagram, skipping the keto ...

  6. Nuclear magnetic resonance spectroscopy of carbohydrates

    en.wikipedia.org/wiki/Nuclear_magnetic_resonance...

    Carbohydrate NMR spectroscopy is the application of nuclear magnetic resonance (NMR) spectroscopy to structural and conformational analysis of carbohydrates.This method allows the scientists to elucidate structure of monosaccharides, oligosaccharides, polysaccharides, glycoconjugates and other carbohydrate derivatives from synthetic and natural sources.

  7. Arabinose - Wikipedia

    en.wikipedia.org/wiki/Arabinose

    For biosynthetic reasons, most saccharides are almost always more abundant in nature as the "D"-form, or structurally analogous to D-glyceraldehyde.[note 1] However, L-arabinose is in fact more common than D-arabinose in nature and is found in nature as a component of biopolymers such as hemicellulose and pectin.

  8. List of sugars - Wikipedia

    en.wikipedia.org/wiki/List_of_sugars

    Brown sugar [1] – Consists of a minimum 88% sucrose and invert sugar. Commercial brown sugar contains from 4.5% molasses (light brown sugar) to 6.5% molasses (dark brown sugar) based on total volume. Based on total weight, regular commercial brown sugar contains up to 10% molasses. Buttered syrup [1]

  9. Glyceraldehyde - Wikipedia

    en.wikipedia.org/wiki/Glyceraldehyde

    The stereochemical configuration can only be determined from the chemical structure, whereas the optical rotation can only be determined empirically (by experiment). It was by a lucky guess that the molecular D-geometry was assigned to (+)-glyceraldehyde in the late 19th century, as confirmed by X-ray crystallography in 1951. [5]
