Lactose is a disaccharide in which a glycosidic linkage connects the monosaccharides galactose and glucose. OH НО OH (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. Но ОН НО ОН ОН Lactose

4. An iterative approach to oligosaccharide synthesis involves the use of protected glycals (sugars with C1-C2 double bond) as shown below. The product from the reaction of the first glycal with DMDO under anhydrous conditions is treated with another suitably-protected glycal to form a disaccharide glycal, and the process can be repeated to form a trisaccharide glycal, and so on... Crucial to the success of this approach is the stereoselective formation of the intermediate A in the scheme below. Draw the structure of A. DMDO CH₂Cl2 A OH ZnCl₂, THF OH
