Luckygamer Posted December 25, 2010 Share Posted December 25, 2010 I recieved a ball and stick model set for Christmas. I don't understand why this Glucose is named the way it is. I found information on D-Glucose, but nothing with the + in the middle. Is it the same thing? Link to comment Share on other sites More sharing options...

The +/- notation refers to which way the compound rotates plane polarized light, "+" for clockwise and "-" or counter-clockwise. The D/L systems refers to how a compound compares to glyceraldehyde in terms of chirality. The D/L system and +/- systems both refer to the chirality of a compound but there is no correlation between the two. Link to comment Share on other sites More sharing options...
Horza2002 Posted December 25, 2010 Share Posted December 25, 2010 As Mississippichem has said, its to do with how you'r determinging the stereochemistry. Unforuntantly, D/L, +/- and R/S labells are all unrelted to ach other Link to comment Share on other sites More sharing options...
Luckygamer Posted December 25, 2010 Author Share Posted December 25, 2010 So D-Glucose is unrelated to D-(+)-Glucose? Link to comment Share on other sites More sharing options...
mississippichem Posted December 25, 2010 Share Posted December 25, 2010 So D-Glucose is unrelated to D-(+)-Glucose? D-Glucose happens to be a "+" compound. So D-Glucose is said to be D(+)Glucose. Link to comment Share on other sites More sharing options...
Luckygamer Posted December 26, 2010 Author Share Posted December 26, 2010 I see, so one last question. Is D-Glucose known as Dextrose? Thank you for all of your help. I have learned alot. Link to comment Share on other sites More sharing options...

Yes, but "D-Glucose" is preferred because it is more systematic. Link to comment Share on other sites More sharing options...
