  2. Osazone - Wikipedia

    en.wikipedia.org/wiki/Osazone

    Osazone are a class of carbohydrate derivatives found in organic chemistry formed when reducing sugars are reacted with excess of phenylhydrazine at boiling temperatures. [ 1 ] [ 2 ] Formation

  3. Carbohydrate - Wikipedia

    en.wikipedia.org/wiki/Carbohydrate

    Lactose is a disaccharide found in animal milk. It consists of a molecule of D-galactose and a molecule of D-glucose bonded by beta-1-4 glycosidic linkage.. A carbohydrate (/ ˌ k ɑːr b oʊ ˈ h aɪ d r eɪ t /) is a biomolecule consisting of carbon (C), hydrogen (H) and oxygen (O) atoms, usually with a hydrogen–oxygen atom ratio of 2:1 (as in water) and thus with the empirical formula C m ...

  4. Amino sugar - Wikipedia

    en.wikipedia.org/wiki/Amino_sugar

    Glucosamine. In organic chemistry, an amino sugar is a sugar molecule in which a hydroxyl group has been replaced with an amine group.More than 60 amino sugars are known, with one of the most abundant being N-acetyl-D-glucosamine (a 2-amino-2-deoxysugar), which is the main component of chitin.

  5. Glycosaminoglycan - Wikipedia

    en.wikipedia.org/wiki/Glycosaminoglycan

    The fourth class of GAG, hyaluronic acid (HA), is not sulfated and is synthesized by three transmembrane synthase proteins HAS1, HAS2, and HAS3. HA, a linear polysaccharide, is composed of repeating disaccharide units of →4)GlcAβ(1→3)GlcNAcβ(1→ and has a very high molecular mass, ranging from 10 5 to 10 7 Da. Each HAS enzyme is capable ...

  6. Mannose - Wikipedia

    en.wikipedia.org/wiki/Mannose

    Mannose is a sugar with the formula HOCH 2 (CHOH) 4 CHO.It is one of the monomers of the aldohexose series of carbohydrates.It is a C-2 epimer of glucose.Mannose is important in human metabolism, especially in the glycosylation of certain proteins.

  7. Oligosaccharide nomenclature - Wikipedia

    en.wikipedia.org/wiki/Oligosaccharide_nomenclature

    An oligosaccharide has both a reducing and a non-reducing end. The reducing end of an oligosaccharide is the monosaccharide residue with hemiacetal functionality, thereby capable of reducing the Tollens’ reagent, while the non-reducing end is the monosaccharide residue in acetal form, thus incapable of reducing the Tollens’ reagent. [2]

  8. Oligosaccharide - Wikipedia

    en.wikipedia.org/wiki/Oligosaccharide

    Lectins, or proteins that bind carbohydrates, can recognize specific oligosaccharides and provide useful information for cell recognition based on oligosaccharide binding. [citation needed] An important example of oligosaccharide cell recognition is the role of glycolipids in determining blood types.

  9. Monosaccharide - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide

    Monosaccharides are the simplest units of carbohydrates and the simplest form of sugar. If the carbonyl is at position 1 (that is, n or m is zero), the molecule begins with a formyl group H(C=O)− and is technically an aldehyde. In that case, the compound is termed an aldose.
