Sentences with phrase «enantiomer in»
These strategies are: (1) physical separation by temporarily converting the two enantiomers into two diastereomers (called resolution); (2) physical separation in a chiral chromatographic environment; (3) chemical discrimination in a chiral environment (using enzymes or other chiral platforms as chemical reagents); and (4) asymmetric synthesis of one enantiomer in preference to the other.

Although their atoms are connected in exactly the same sequence, the two enantiomers are distinct mirror images, like a pair of hands.
This relies on the fact that solutions of pure enantiomers rotate the plane of polarisation of light passing through them; opposite enantiomers rotate it in opposite directions.
Organic molecules in which four different chemical groups are attached to a central carbon atom are also chiral, as they too can be constructed in two forms, usually labelled d and l and known as enantiomers.
Furthermore, since AMD070 and related (S)- enantiomers were previously demonstrated to have a significant increase in potency, representative compounds from the pyridine 142, the thiophene 146 and the furan 149 series were synthesized as the (S)- enantiomers, resulting in compounds with an IC50 value of 4.2, 1.0, and 0.3 nM, respectively.
When derivatives were resolved in single enantiomers, compounds with S - configuration at the chiral center showed higher CXCR4 antagonistic activity with respect to the corresponding R - isomers.
Regarding my particular interests in organic synthesis, we always have to deal with chiral molecules which are present in nature as single enantiomers.
The majority of naturally occurring (plant and animal) substances for which stereoisomers are possible exist in nature as single enantiomers.
Because laboratory chemical reactions are not usually conducted in chiral environments, they will produce 1:1 (racemic) mixtures of enantiomers.
Naturally occurring vitamin E is a family of compounds, all members of which are chiral and only one enantiomer of each occurs in nature, so taking alpha - tocopherol doesn't meed the body's need of vitamin E.
Though glucose and fructose are enantiomers, in other words their molecular structures are mirror images of each other and they are completely different and act different too.
