additonal notes Flashcards
is a functional group that is always present in a carbohydrate molecule
Hydroxyl
the complete hydrolysis of polysaccharides produce many —–
monosaccharides
is the handedness in molecules
Chirality
a form of isomerism
handedness
is when compounds have the same molecular formula but is structurally different
isomerism
2 kinds of mirror images in chirality
superimposable mirror images
non-superimposable mirror images
coincide at all points when the images are laid upon each other
Superimposable mirror images
not all points coincide when the images are laid upon each other
non-superimposable mirror images
exists in left and right-handed forms
non-superimposable mirror images
is the structural requirement for handedness
Chirality
is the presence of carbon atom that has four different groups bonded to it in a tetrahedral orientation
Chirality
a molecule that has a chiral center
chiral
whose mirror images are nonsuperimposable
chiral molecule
whose mirror images are superimposable
achiral molecule
gives forms that are biologically active, each form giving a different property, effectiveness , response
chirality
have the same molecular and structural formula but differ in the orientation of atoms in space
stereoisomers
the stability of a molecule’s structure or how resistant it is to changes in shapes
structural rigidity
are stereoisomers whose mirror images are nonsuperimposable
Enantiomers
stereoisomers whose molecules are not mirror images of each other
Diastereoisomers
a 2-dimensional structural notation for showing the spatian arrangement of groups about chiral centers in molecules
Fischer projection formula
are diastereomers whose molecules differ only in the configuration at one chiral center
Epimers
a compound that rotates the plane of polarized light
Optically active compound
a chiral compound that rotates the plane of polarized light in clockwise direction
Dextrorotatory
a chiral compound that rotates the plne of polarized light in a counterclockwise direction
Levorotatory compound
