Because of their unique properties, enantiomers (pairs of mirror-symmetric, nonsuperimposable molecules that differ only in optical activity and their interaction with other chiral molecules) have been instrumental in demonstrating that olfactory perception relies on molecular shape. To investigate how ...
at the stereogenic centre, two isomers present in the molecule differ, while the rest remains identical. a molecule may contain numerous stereocenters leading to several stereoisomers. stereoisomers are isomeric molecules that possess the same constitution and molecular formula, but they vary in three...
When two diastereomers differ at only one stereocenter, they are referred to as epimers. These isomers vary in physical properties and chemical reactivity. An illustration of enantiomers that are mirror images of each other is provided below. ...
(A) Mean EOG amplitudes (base-to-peak) AN1 and (peak-to-peak) AP1N1 of (−)- and (+)-rose oxide differ significantly (*p < 0.05), with higher amplitudes in response to (+)-rose oxide. (B) EOG peak latencies TP1 and TN1 of each participant in response to (−)- and...

However, the lack of activity at GABAARs and further study of enantiomeric steroids has resulted in identification of unexpected actions of these agents – actions that suggest strongly that unnatural NAS analogues may have unique therapeutic potential that can both complement and differ from the ...
The body only uses L amino acids, and proteins are chains of amino acids that in the most simple sense fold up into a single structure by themselves when they are formed. Do you think a cell could live with all D (...
been reported that the enantiomers differ in their biological activi- ties related to CNS side effects [10,11]. The stereo-selective passage of MQ through the blood-brain barrier in rats was investigated by Baudry et al. [8]. They found higher concentrations of the (+)- ...
The observation that changes in membrane cholesterol levels alter the pattern of EGF receptor phosphorylation suggests that the extent of activation of individual downstream signaling pathways by EGF could differ depending on the level of cholesterol in the cell membrane. As a variety of pathological ...
which are themselves coupled by a radiation field, where the superposition state is comprised of states which differ in their symmetry with respect to reflection through a plane which interchanges the L and D enantiomers, and then allowing the mixture to radiate spontaneously to the ground electroni...
