<p>Allyl α-D-galactopyranoside is a colorimetric reagent that reacts with the polysaccharides to form a colored product. The reaction is based on the transfer of an allyl group from the reagent to the polysaccharide. This reaction can be performed using atomic force microscopy and microscopy techniques, as well as using light and UV-visible spectroscopy. The reaction can also be used to measure glycopolymer concentrations. A titration procedure has been developed for this purpose, in which an excess of allyl α-D-galactopyranoside is added to a solution containing galactose and ammonium sulfate. Allyl α-D-galactopyranoside reacts with galactose to produce an insoluble precipitate that can be measured by weighing or using optical density measurements at a certain wavelength.</p>

<p>5-Deoxy-L-ribose is found in a variety of organisms, including humans. It is stereoselective, with the (-) form being more common than the (+) form. 5-Deoxy-L-ribose is synthesized by the glycosidic bond between l-arabinose and D-ribose. This compound is an inexpensive way to produce 5-deoxy analogs of other sugars, such as glucose, fructose, and mannose. The biosynthesis of 5-deoxy-L-ribose relies on a molybdenum cofactor and involves oxidation of L-arabinonate by aldehyde oxidase to give L-xylulose.
