What is the configuration of the monosaccharide if the OH group on the penultimate carbon is oriented to the left?

L-Configuration

2
New cards

What is a point in a molecule where swapping any two groups creates a different stereoisomer, which can be an atom with three or four groups, including double bonds?

Stereocenter

3
New cards

What is a type of stereocenter that is specifically a carbon atom bonded to four different single-bonded groups, leading to non-superimposable mirror images (enantiomers)

Determine the type of isomerism:

stereoisomers that are mirror images but not superimposable

Enantiomers (Eh-non-tiomers)

12
New cards

Determine the type of isomerism:

stereoisomers that are non-superimposable, non-mirror images

Diastereomers

13
New cards

Determine the type of isomerism:

diastereomers that differ from each other in configuration at only one chiral carbon (other than the anomeric) atom

Epimers

14
New cards

Determine the type of isomerism:

These are isomers obtained from the change of position of hydroxyl group attached to the anomeric carbon

Anomerism

<p>Anomerism</p>
15
New cards

a carbon that, in the acyclic form, is not a stereocenter, but once it takes on the cyclic form, it becomes a stereocenter

Anomeric Carbon

16
New cards

Determine the type of isomerism:

Occurs when two similar groups are attached to the same or opposite sides of a double bond (in open-chain form) or across a ring structure (in cyclic form).
