19
Q

Phenomenon in which a molecule forms isomers that have the same composition but that differ in the orientation of those parts in space.

A

Stereoisomerism

20
Q

two kinds of stereoisomers

A

enantiomers and diastereomers.

21
Q

pair of molecules that exist in two forms that are mirror images of one another but cannot be superimposed one upon the other.

A

ENANTIOMERS

22
Q

are not related as object and mirror image and are notenantiomers. Unlike enatiomers whichare mirror imagesof each other andnon-sumperimposable, diastereomers arenot mirror imagesof each other andnon-superimposable

A

DIASTERIOMERS

23
Q

the structure of Glucose can be represented in 3 ways

A
  1. Straight-chain Form
  2. Cyclic Structure (Fisher-Haworth Projection)
  3. Chair Form (3D Form)
24
Q

the Cyclic Projection of the structure of Glucose

A

Fisher-Haworth Projection

25
Q

thermodynamically stable
the molecules viewed from the side and above the plane of the ring; the bonds nearest to the viewer are bold and thickened, and the hydroxyl groups are above or below the plane of the ring.

A

Fisher-Haworth Projection

26
Q

is an isomer of glucose that has -OH group present on the first carbon atom is on the same side as that of the CH2OH molecule group.

A

Alpha Glucose

27
Q

is also an isomer of D-glucose in which the -OH group placed on the first carbon atom is placed on the opposite side of the CH2OH group.

A

Beta Glucose

28
Q

When the –OH group is on the right, the sugar is

A

D-isomer (DEXTRO)

29
Q

When the –OH group is o the left, the sugar

A

L-isomer (LEVO)

30
