The structure of the original oligosaccharide is to be determined that contains twoglucose residues and one galactose residue. It produces two glucose with methoxygroupat 2,3, and 6 position and galactose with methoxy group at 2,3,4, and 6 positions, when exhaustive methylationfollowed by subsequent hydration is performed. Introduction: Oligosaccharides are the polymers that contain 10 to15 monomers linked together by glycosidic bonds. Exhaustive methylation is a process where a sugar molecule is treated with a methylating agent exhaustively till the methyl groupsare added to all the possible locations. This converts OH (hydroxyl) groups toOCH3 (methoxy group). However, the glycosidic bonds are not affected due to exhaustive methylation.

B- Vitamins are converted readily into important metabolic cofactors. Deficiency inany one of them has serious side effects. a. The disease beriberi results from a vitamin B 1 (Thiamine) deficiency and ischaracterized by cardiac and neurological symptoms. One key diagnostic forthis disease is an increased level of pyruvate and α-ketoglutarate in thebloodstream. How does this vitamin deficiency lead to increased serumlevels of these factors? b. What would you expect the effect on the TCA intermediates for a patientsuffering from vitamin B 5 deficiency? c. What would you expect the effect on the TCA intermediates for a patientsuffering from vitamin B 2 /B 3 deficiency?
