7.1.1 Which rоw оf the tаble shоws which of these sugаrs аre monosaccharides and which are disaccharides? (Choose the correct option between A, B, C and D) Mono Saccharide Disaccharide A Fructose only Glucose and Sucrose B Glucose only Fructose and Glucose C Fructose and Glucose Sucrose only D Glucose and Sucrose Fructose only (1) 7.1.2 Which type of bond joins two monosaccharides together to form a disaccharide? (1) A ester B glycosidic C peptide D phosphodiester 7.2 The table shows the concentration of these sugars in three pineapples. Table 7.2 Sugar Concentration of sugar /g cm-3 Pineapple 1 Pineapple 2 Pineapple 3 fructose 1.71 1.44 1.41 glucose 1.22 1.02 1.00 sucrose 9.08 7.77 8.81 7.2.1 Calculate the mean concentration of glucose in these three pineapples. Give your answer in g dm−3. (2) 7.3 Pineapples can be preserved by a process called osmotic dehydration in which pieces of pineapple are submerged in a solution of sugars. Figure 7.3 (see addendum Question 7) shows how this process can be carried out. Osmotic dehydration helps to preserve the pineapple by reducing the water content. Osmotic dehydration also ensures that the concentration of each sugar in the pineapple does not change. This preserves the sweet taste of the pineapple. 7.3.1 Explain what the solution of sugars should contain to preserve pineapples. Use the information in Table 7.2 to support your answer. (6)
