(a) Identify the glycosidic linkage and the acetal carbon
in lactose.
(b) What type of glycosidic linkage does lactose have
(i.e., is it 1,1'-, 1,2'-, etc., and is it a or B)?
(c) People who are lactose intolerant are deficient in
the enzyme lactase, and therefore cannot efficiently
break down the disaccharide into its monosaccharides. When lactose is treated with aqueous acid, however, this
hydrolysis can take place, though relatively slowly. Draw the complete, detailed mechanism and the products of the
acid-catalyzed hydrolysis of lactose.
