Answer ALL parts of this question. The structure shown below is that of one of the optical isomers of the well-known analgesic, ibuprofen: (a) (b) (c) CH₂ H₂C-A C H₂ 2048 ÇO,H CH CH₂ Explain how the Cahn Ingold Prelog sequence rules can be used to rank groups in order of priority, using the four groups attached to the chiral centre in ibuprofen as illustrated. Based on the order of priority of the four groups determined in part (a) of this question, explain which of the two enantiomers (R or S) of ibuprofen is shown. S Draw the structure of the enantiomer of this compound and comment on why it might produce a different reaction in vivo (in fact the enantiomer has no analgesic effect).
Carbohydrates
Carbohydrates are the organic compounds that are obtained in foods and living matters in the shape of sugars, cellulose, and starch. The general formula of carbohydrates is Cn(H2O)2. The ratio of H and O present in carbohydrates is identical to water.
Starch
Starch is a polysaccharide carbohydrate that belongs to the category of polysaccharide carbohydrates.
Mutarotation
The rotation of a particular structure of the chiral compound because of the epimerization is called mutarotation. It is the repercussion of the ring chain tautomerism. In terms of glucose, this can be defined as the modification in the equilibrium of the α- and β- glucose anomers upon its dissolution in the solvent water. This process is usually seen in the chemistry of carbohydrates.
L Sugar
A chemical compound that is represented with a molecular formula C6H12O6 is called L-(-) sugar. At the carbon’s 5th position, the hydroxyl group is placed to the compound’s left and therefore the sugar is represented as L(-)-sugar. It is capable of rotating the polarized light’s plane in the direction anticlockwise. L isomers are one of the 2 isomers formed by the configurational stereochemistry of the carbohydrates.
