The [sup.13]C NMR spectrum of 3 contains peaks at 13.16 ppm for methyl group bound to steroid nucleus; at 21.66-114.44, 124.60, and 132.46-154.76 ppm for steroid moiety; at 115.30, 125.00-129.36, and 163.56 ppm for phenyl bound to amide group; at 170.32 ppm for amide group; and at 219.76 ppm for ketone group. Finally, the presence of compound 3 was further confirmed from mass spectrum which showed a molecular ion at m/z 415.18.
It was logical to assume that [alpha], [beta]-unsaturated ketone group in the each diterpenoids could undergo the nucleophilic addition with nucleophile compounds such as L-cysteine in DMEM.
Since sugar alcohols are modified to exhibit different physical properties than sugar, they can be used in products labeled sugar-free or no added sugar." Sugar alcohols, also referred to as polyols, are polyhydric alcohols which are closely related to sugars, but with their aldehyde or ketone group replaced by a hydroxyl group.
Moreover, the catalytic antibodies facilitate the reaction at one specific ketone group in a molecule containing another similar ketone -- a feat previously impossible, says Schultz.
