Stereoisomer

However, the complexity of a thermodynamically stable sugar stereoisomer has only two possibilities: D or L depending upon whether the C-O ring bond points “up” or “down”. ❋ Unknown (2006)

A stereoisomer can have any chemical properties any other molecule can, relatively unrelated biologically, their general properties will be similar. ❋ Unknown (2006)

It is, however, the wrong stereoisomer mirror image - this no links thing is getting really annoying; isn't this the point of comment moderation? ❋ Unknown (2006)

After several trials, the researchers determined that nickel catalysts, which share similar properties to palladium materials, allowed the α-ketoesters to add to nitroalkenes with high yields and purity; over 90% of the final product corresponded to a specific stereoisomer, a molecule with a hard-to-achieve, geometrically distinct structure. ❋ Unknown (2010)

"Because of its intense sweetness, the R, R stereoisomer in particular should be economically competitive compared to other high intensity sweeteners." ❋ [email protected] (2010)

Lexapro (escitalopram) is the S-stereoisomer of the earlier Lundbeck drug Celexa (citalopram). ❋ Unknown (2010)

Thalidomide, for instance, is a powerful, safe anti-nausea drug, but it’s stereoisomer causes nasty birth defects. ❋ Unknown (2006)
