  2. Dehydration reaction - Wikipedia

    en.wikipedia.org/wiki/Dehydration_reaction

    The classic example of a dehydration reaction is the Fischer esterification, which involves treating a carboxylic acid with an alcohol to give an ester RCO 2 H + R′OH ⇌ RCO 2 R′ + H 2 O Often such reactions require the presence of a dehydrating agent, i.e. a substance that reacts with water.

  3. Monosaccharide - Wikipedia

    en.wikipedia.org/wiki/Monosaccharide

    These specific monosaccharide names have conventional three-letter abbreviations, like "Glu" for glucose and "Thr" for threose. Generally, a monosaccharide with n asymmetrical carbons has 2 n stereoisomers. The number of open chain stereoisomers for an aldose monosaccharide is larger by one than that of a ketose monosaccharide of the same length.

  4. Nucleotide sugar - Wikipedia

    en.wikipedia.org/wiki/Nucleotide_sugar

    Cytidine Diphosphate: CDP-D-Ribitol (i.e. CMP-[ribitol phosphate]); [8] though not a sugar, the phosphorylated sugar alcohol ribitol phosphate is incorporated into matriglycan as if it were a monosaccharide. In other forms of life many other sugars are used and various donors are utilized for them.

  5. Reducing sugar - Wikipedia

    en.wikipedia.org/wiki/Reducing_sugar

    Reducing form of glucose (the aldehyde group is on the far right). A reducing sugar is any sugar that is capable of acting as a reducing agent. [1] In an alkaline solution, a reducing sugar forms some aldehyde or ketone, which allows it to act as a reducing agent, for example in Benedict's reagent.

  6. Barfoed's test - Wikipedia

    en.wikipedia.org/wiki/Barfoed's_test

    Barfoed's test is a chemical test used for detecting the presence of monosaccharides. It is based on the reduction of copper(II) acetate to copper(I) oxide (Cu 2 O), which forms a brick-red precipitate. [1] [2] RCHO + 2Cu 2+ + 2H 2 O → RCOOH + Cu 2 O↓ + 4H + (Disaccharides may also react, but the reaction is much slower.)

  7. Large meals after 5 pm could contribute to type 2 diabetes risk

    Consuming more than 45% of daily calories after 5 p.m. can contribute to greater risk of type 2 diabetes, cardiovascular problems, and chronic inflammation, a recent study suggests.

  8. Glycosidic bond - Wikipedia

    en.wikipedia.org/wiki/Glycosidic_bond

    The reaction often favors formation of the α-glycosidic bond as shown due to the anomeric effect. A glycosidic bond is formed between the hemiacetal or hemiketal group of a saccharide (or a molecule derived from a saccharide) and the hydroxyl group of some compound such as an alcohol. A substance containing a glycosidic bond is a glycoside.
