What is the most important part of deamination? The enzymatic removal of the amino group (NH2) from amino acids. What would happen without the regulation of GDH and other deaminating enzymes?
Synthetic marijuana is far more powerful, and it just depends on the compounds that are in the synthetic cannabinoid. The compounds itself, it's almost like a DNA, like little piece of DNA, and some of the analogs could be 1 to 800 times more powerful, some are 25 times more powerful, some are 5 times.
Since the term synthetic does not apply to the plant but rather to the chemical that the plant contains (tetrahydrocannabinol), the term synthetic cannabinoid is more appropriate. Research on the safety of synthetic cannabinoids is now becoming available.
