There are many chemical molecules whose names are Cannabigerol (CBG), cannabidol (CBD), cannabichromene (CBC), tetrahydrocannabivarin (THCV), cannabigerovarinic acid (CBGV) and cannabidiolic acid (CBDA) derived from Marijuana. Theoretical methods were used to compare the chemical and biological activities of the six major molecules. Molecules were compared with their chemical activities using m...
Nuclear magnetic resonance (NMR) is the most widely used nondestructive technique in analytical chemistry. In recent years, it has been applied to metabolic profiling due to its high reproducibility, capacity for relative and absolute quantification, atomic resolution, and ability to detect a broad range of compounds in an untargeted manner. While one-dimensional (1D) (1)H NMR experiments are p...
The proton nuclear magnetic resonance spectra of several chloroperoxidase-inhibitor complexes have been investigated. Titrations of chloroperoxidase with azide, thiocyanate, cyanate, or nitrite ions indicate that only the chloroperoxidase-thiocyanate complex exhibits slow ligand exchange on the 360-MHz NMR time scale. The temperature dependence of the proton NMR spectra of the complexes suggest...
