When two a-glucose monomers join during polymerization, the new C—O—C bond that is formed is called a glycosidic linkage. We showed you in the chapter which OH group on one of the monomers is used for this linkage. However, when it joins to the other monomer, a different OH group is the site of connectivity. Examine the starch polymer as pictured on page 746 and then indicate which OH group is the site of connectivity. If the glycosidic linkage is formed from two OH groups, then what small molecule do you reason splits off during the linkage formation?
