Monosaccaridi

Methyl β-L-arabinopyranoside is a stereochemically pure monosaccharide that has been used to calibrate and quantify the conformational, stereochemical, and spectrometric methods. Methyl β-L-arabinopyranoside has a conformation that is restricted by the presence of an α-hydroxyl group at C2. The chloride ion can be used to monitor this conformation. The diameter of methyl β-L-arabinopyranoside can be measured with a micropipette and monitored using an aerosol detector. Methyl β-L-arabinopyranoside can also be quantified by mass spectrometry or spectrophotometry. The conformational, stereochemical, and spectrometric methods have been calibrated using methyl β-L-arabinopyranoside as a standard to determine their accuracy in measuring the size of other molecules.
