Chiral centers of glucose
WebI) All of its chiral centers in the enantiomer are in a different orientation from the D-form (i.e. if a hydroxyl is up in D, it is down in the enantiomer, etc.) II) The sugar would have the same base name as the D-form (i.e. like D-glucose and L-glucose have the same base name) answer choices: Only I. Only II. Both I and II. Neither I nor II WebThese two stereoisomers. They're a special type of stereoisomer that we call enantiomers. We'll talk much more about number of stereoisomers in a later video. The next video, we're going to go into more detail about chiral centers and chirality centers, and how to identify the number of chiral centers in a molecule. Up next: video.
