Many biomolecules contain the same atoms bonded to the same atoms so they have the same molecular formula. Enantiomers are isomers of this type that are mirror images of each other and cannot be superimposed on each other. All properties of enantiorners are identical except they rotate the plane of polarized light in opposite directions and
a. they react differently with non-chiral compounds
b. they have different specific gravities
c. an enzyme that binds one of the enantiomers won't be able to bind with the other
d. one will usually dissolve in water wile the other will not
e. they have different molecular weights because of slightly different isotopes they contain
Answer : Option(c) is correct
Explanation: Enantiomers are the isomers which have same chemical formula but they form non super imposable mirror image to each other. As we know that enzymes are always specific to the site (Steriospecific) where they attach to show the reaction . Due to the two different forms the enzyme specifically can not bind to the same position on the both enantiomers. so an enzyme that binds one of the enantiomers won't be able to bind with the other .

A. Enantiomers: Certain substances have the unique property of rotating the plane of plane-polarized light. Such light rotation is detectable with the aid of a polarimeter. In order for a molecule to be optically active it must be chiral. Chiral objects lack a plane of symmetry and are non-superimposable on their mirror images. A sp?- hybridized carbon atom can fulfill these requirements if all four of its substituents are different. 1. Methane a) Prepare a methane molecule and then substitute...
Match the following definitions with the correct type of isomer. : Two or more coordiantion compounds with the same composition in which the complex ions have different ligand arrrangements. Linkage Isomers Coordination Isomers : Molecules with the same chemical formula and the same connection of atoms but differ in the spatial arrangements of the atoms. Geometric Isomers : Coordination compounds with the same compositions but with different ligand donor atoms linked to the central metal ion. Optical Isomers : A...

3. Cyclic compounds The presence of the ring in all but very large ring cyclic molecules prevents full rotation of the ring atoms. For this reason, stereoisomerism may also occur in cyclic molecules. a) Prepare a model of cyclohexane, C6H12. Draw the condensed formula. b) Build a model of methylcyclohexane (C7H14) by replacing one of the hydrogens of cyclohexane with a methyl group.

Week 10- Constitutional isomers Constitutional isomers have the same molecular formula, but their atoms are bonded in different orders. These may be further distinguished as chain isomers, which differ only in hydrocarbon chain structure, positional isomers, which differ in the location of a functional group, and functional group isomers which differ in the nature of their functional groups. Typically chain and position isomers show only modest differences in their physical and chemical properties, while functional group isomers differ greatly from...

PART 3: 2,3-BUTANEDIOL CH-CH(OH)-CH(OH)-CH, mirror images, not superimposable Build as many models of 2,3-butanediol as you can. First, attach two carbons with a single bond. To each carbon add one carbon, one hydrogen, and one oxygen. To complete the structure, Ti the remaining hydrogen atoms. Remember, a model is not different if it is completely superimposable on one already constructed! 13. How many stereochemically different models are possible for 2,3-butanediol? 14.
