You discovered a potential new drug molecule, which binds to its target with a binding free energy of -41.0 kJ/mol at 37 °C. You are performing additional experiments in order to improve the binding affinity of the drug. Select all of the possible modifications that could improve binding. O A phenyl group at another site of the drug increases the association constant by a factor of 5. O You engineer a new hydrogen bond to be formed between the drug and the target. O The addition of an alcohol function in another side of the drug molecule reduces the dissociation constant of the drug-target complex by a factor of 10. O The addition of a methyl group at one specific site of the drug moecule results in a binding free energy of -40.5 kJ/mol.
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.
