The entropy difference between the two kinds of crystal is estimated from the dispersion curves, and compared with that obtained previously. It is suggested that the main cause for the entropy difference between two isomers is the difference in the strength of the hydrogen bond, and that the ...
The structural isomers have an equal molecular formula, but the connections or their order is different. The stereoisomers are molecules with the same sequence of bonded atoms and molecular formula, but with different 3D configurations/orientations of their atoms. Anomers and epimers are two types ...
THE difference between the odours of the two optical isomers of carvone has been recognized for some time; (+)-carvone (isolated from caraway oil) was characterized as caraway-like while (−)-carvone (isolated from spearmint oil), as spearmint-like 1 . Samples purified by gas–liquid chroma...

Two isomers of the aldohexose sugars are known as glucose,of which only one (D-glucose) is biologically active.The mirror-image of the D-glucose ,L-glucose, cannot be used by cells.In solutions, the open-chain form of glucose (either 'D-' or 'L-') exists in equilibrium with several...

The main differences between Celexa and Lexapro are: Celexa is a branded version of citalopram and Lexapro is a branded version of escitalopram Citalopram is a mixture of two stereo-isomers: R-citalopram and S-citalopram. Stereo-isomers are compounds that have the same chemical formula but differ...

The metabolic network between astaxanthin synthesis and pyruvate metabolism was proposed. The mechanism by which high astaxanthin production was obtained by non-motile cells as seeds was dissected. The results provide a new entry point to improve the astaxanthin productivity....
