1. Maltose, trehalose, and cellobiose are all disaccharides of glucose that differ in the nature of the glycosidic bond attaching the two glucosyl residues. In maltose, the linkage is α(1→4); in trehalose, the linkage is α(1→1); in cellobiose the linkage is β(1→4). Based upon this information,which of these disaccharides is a non-reducing sugar? Explain your reasoning. Which of these disaccharides results from the breakdown of cellulose? Explain your reasoning. Which of these disaccharides results from the breakdown of amylose? Explain...
