1.004 0.000 1.125 6.640The calculated solute descriptors values are in bold. The overall standard deviation for
the predicted solutes descriptors for ketamine is 0.041 log unit. Although the calculated
descriptor A shows no ability of hydrogen bond, A is zero; it's obvious that ketamine has some
hydrogen bond ability by looking at its structure. There is one hydrogen donor in ketamine
structure. The molecule shows some tendency of being basic with the nitrogen element. The
chlorine, nitrogen and oxygen element emphasize the polarity effect on ketamine; thus the S
descriptor is 1.004. One can expect a high value on the polarity descriptor, but as mentioned
early on, the S and L descriptors both have dipolarity and polarizability include in their
parameter which makes it harder to know the exact distribution of polarity, dispersion and induce
effects in the coefficient of these parameters. The dipole -dipole interaction depend on the
orientation of the molecule. Ketamine is considered a dissociative anesthetic, which means the
drug distorts the users' perception of sight and sound, and produces feelings of detachment from
the environment.
