Summary Caffeine is a stimulant for the central nervous system which will relax the muscle and increase the gastric acid and heart rate (Kelly‚ 2017). The analyzing of caffeine and caffeine metabolites in saliva is to quantitatively measure the ratio of concentrations of caffeine and metabolites. There are three different metabolites of caffeine and the majority of caffeine metabolite is paraxanthine. The ratio of concentration represents the activity of the first metabolism enzyme of caffeine‚ CYP1A2

Alkyl Halides Alkyl halides are a class of compounds where a halogen atom or atoms are bound to an sp3 orbital of an alkyl group. CHCl3 (Chloroform: organic solvent) CF2Cl2 (Freon-12: refrigerant CFC) CF3CHClBr (Halothane: anesthetic) Halogen atoms are more electronegative than carbon atoms‚ and so the C-Hal bond is polarized. H H μ C + C-l δ δ H The C-X bond is polarized in such a way that there is partial positive charge on the carbon and partial negative charge on the halogen. Dipole moment
