Interpretation Introduction

Interpretation:

The understanding of the specificity of bacterial oxidation for commercial synthesis of the compound vitamin C is to be explained.

Concept Introduction:

▸ The chemical name for vitamin C is L-ascorbic acid. It is obtained commercially by converting the D-sorbitol into the L-ascorbic acid with the formation of an 2ketoLgluconic acid as its intermediate.

▸ The process involves two major steps which are the formation of Lsorbose form Dglucose and the second is the bacterial oxidation of D-Glucitol by the use of a microorganism, A. suboxydans.

One step in the gluconeogenesis pathway for the biosynthesis of glucose is the partial reduction of 3-phosphoglycerate to give glyceraldehyde 3-phosphate. The process occurs by phosphorylation with ATP to give 1,3-bisphosphoglycerate, reaction with a thiol group on the enzyme to give an enzyme-bound thioester, and reduction with NADH. -OPO3²- Enz-SH H-C-OH ATP CH₂OPO3²- 3-phosphoglycerate O 0-0--0 O ADP CH₂CH3 substitute for 1,3-bisphosphoglycerate C H-C-OH CH₂OPO3²- 1,3-bisphosphoglycerate O=C CH3-SH substitute for Enz-SH H H-C-OH | CH₂OPO3²- PO4³- O.

Assume a basic group on the enzyme catalyzes the formation of this intermediate. To simplify the drawing process, substitute the structures below for the 1,3-bisphosphoglycerate and Enz-SH.

1. Trehalose is a disaccharide that can be obtained from fungi, sea urchins and insects. Acid hydrolysis of trehalose yields only D-glucose. Trehalose is hydrolysed by α-glucosidase and not by β-glucosidase enzymes. Methylation of trehalose followed by hydrolysis yields two molar equivalents of 2,3,4,6-tetra-O-methyl-D-glucopyranose.From the following experimental data, deduce the structure of trehalose.What will be the effect of trehalose on Fehling’s solution? 2.Suggest a test you will use to show that a given food substance contains protein
Ribose, a carbohydrate with the formula shown, forms a cyclic hemiacetal, which, in principle, could contain either a four-membered, five-membered, or six-membered ring. When D-ribose is treated with methanol in the presence of an acid catalyst, two cyclic acetals, A and B, are formed, both with molecular formula C,H,0, These are separated, and each is treated with sodium periodate (Section 10.8C) followed by dilute aqueous acid. Both A and B yield the same three products in the same ratios. он о CHO СНО H+ CH,OH A +B ÕH 1. NalO, 2.
