excellent video i have a presentation on the importance of drug enatiomers in clinical pharmacology in 2 weeks, and this video has added more knowledge to my work. thanks.

great explanation but one doubt that if there is a mixture of equal concentrations of dextro and laevo isomers of the same compound..doesnt the net optical activity become zero ?

This is slightly misleading in the description of optical rotation. d and l are used to designate optical isomers not D and L. D and L are used for the Fischer definition. If you look at amino acids (19 of the common ones found in proteins are chiral) you will find they are all L but they are not all l or all d - they do not rotate plane polarised light in the same direction. The same goes for common sugears which are all D, but not all d or l. Today we prefer to use (+) in place of d and (-) in place of l for optical isomers to avoid this very confusion.

Hi Gary. Thanks for your constructive feedback. Let me see if i can create an updated video in the future that also helps to explain the use of (+) in place of d and (-) in place of L, for the very reasons that you have mentioned. Thank you once again for bringing this up :-)

Is there any difference between optical isomers and enantiomers.....or they are same

@wondersofchemistry 4 жыл бұрын

Enantiomers are chiral molecules that are mirror images of one another... so yes they are also known as optical isomers :-)

Why did we rotate the d-isomer in the first place? Why didn't we just try to make the two isomers match without rotating anyone of them? Will the result be different or is it gonna be the same?

The ssri Celexa (citalopram) is a combination of both R-citalopram and S-citalopram isomers, while the newer ssri Lexapro (escitalopram) is only the S-citalopram isomer.

what is the difference between chiral and enantiomers

@anandyadav9537 Жыл бұрын

Only chiral carbon forms mirror image?.... if there is a carbon without chiral then it doesn't form mirror images?.......and why does chiral carbon forms mirror images?

@gourabdas4921 Жыл бұрын

There is a wrong concept capital D doesn't indicate rotation.. It must be small d and small l Capital D and L are the configaration of atom or group to a specific atom

@orianagalanou2598 3 жыл бұрын

how can you say that D is the enantiomer that turns the light to the right and L turns it to the left, whilst there are D+, D-, L+ and L- ? thanks in advance.
