(a)[1]
State the type of bond that is formed when polysaccharides are synthesised.
(b)[3]
Disaccharides may be produced either when monosaccharides are synthesised together or when polysaccharides are broken down by hydrolysis. Cellobiose, maltose, sucrose and trehalose are four disaccharides found naturally. Fig. 4.1 displays the molecular structures of these disaccharides. Identify the disaccharides, labelled A to D, from the information given, and write the names of the disaccharides in the spaces provided on Fig. 4.1.
