(ă-kī'răl),
Not chiral; denoting an absence of chirality.

achiral

pertaining to the absence of chirality in a compound, as in stereochemical isomers.

achiral

adjective Referring to a molecule or material which is superimposable on its mirror image—i.e., does not display “handedness”

Enantiomers would only have the same effect if the target binding site were achiral, and pretty much every molecule in your body of reasonable size is chiral.
not resolved by the achiral column, only two peaks are observed.
Based on this information, many attempts have been carried out to synthesize optically active polymers with a stable one-handed helicity from optically inactive achiral vinyl monomers, such as styrene and methyl methacrylate.

Built on the company's UrtraPerforrnance LC (UPLC) technology, the sys tem offers up to 10x shorter run times, reduces solvent usage by as much as 95% and cuts the cost of analyses by as much as 99%, while giving laboratories a greener alternative to normal phase chromatography for chiral and achiral separations.
Hence, a chiral medium gives more freedom to adjust (decrease or increase) the reflection and transmission, because it can be controlled by variation of three parameters ([epsilon], [mu] and k) instead of two parameters ([epsilon] and [mu]) as in the case of achiral medium [2-4].
Enzymatic hydrolysis (using PLE) of achiral compound diethyl-2-methyl-2-((1, 3-dioxoisoindoline-2-yl) methyl) malonate (phthalimido protected [alpha]-methyllysine diester) gives us 2-(ethoxycarbonyl)-2-((1, 3-dioxoisoindolin-2-yl) methyl) Propanoic acid (phthalimido protected [alpha]-methyllysine halfester) with high optical purity.
