below (Hint: Think about the orientation of the monosaccharide). (b) Draw onto the Haworth Projec- tion (template) the mechanistic electron-flow arrows for the cyclization into the pyranose ring. (c) Then draw the "Ci pyranose structure. CH₂OH HO -H H -OH HO -H HO -H Haworth Projection (7 marks) 6. (a) In the box draw the structure of D-Cysteine-L-Glutamic acid (i.c., a dipeptide; D-Cys-L-Glu) at pH 8.0 (see Table 1); (b) Indicate on the structure whether the two chiral centers are R or S, including priorities. (6 marks) 7. Using the Amidomalonate synthesis (as shown below): what alkyl bromide would you use to pre- pare the c-amino acid Lysine (see Table 1)? The product would actually be a mixture of R and S en- antiomers. Draw your answer inside the box for reactant 2. DOCHCH CO,CH,CH, 1.00H₂CH₂ Lysine CH₂ 3. H₂O/Heat (3 marks) O=C HN,
