Glucopyranoside methyl-, a- and

Changes in optical rotation have been popular with those investigating glycoside hydrolysis since Wilhemy in 1850, using the newly invented polarimeter, demonstrated that hydrolysis of glycosides follows the first-order rate equation, k = 1/t log a/(a — x). Rate constants were then ob-tmned for the acid-catalyzed hydrolysis of salicin, - starch, maltose, lactose, methyl a- and /9-n-glucopyranoside, methyl a- and /S-n-galacto-pyranoside, - sucrose, and raffinose. ...
