1.Draw all the mechanism involved in the cyclization of D-Idose to obtain beta- DIdosapyranose

2. If D-Idose is reduced with NHB4, what does it form?

3.) At the laboratory level, a disaccharide was synthesized between beta-D-Glucose and beta-D-Talose via a beta 1-4 glycosidic bond. Form the disaccharide and draw it.

4.Obtain by reductive amination the amino acid isoleucine, draw the mechanism of reaction. Draw the species that can be found of isoleucine at a pH of 1.0 ; 9.0 and point isoelectric

5. Explain all the steps (5 steps) to obtain the Val-Leu dipeptide. Briefly draw the mechanisms to protect the amino group and the acid

6. How would you synthesize a soap from a triglyceride that comes from 1 molecule of acid oleic (CH3 (CH2) 7CH = CH (CH2) 7COOH) and 2 molecules of Lauric acid CH3 (CH2)10COOH. Show How would you prepare it and the products obtained
