I It is produced from guaiacum or wood creosote. Guaiacol acts as a precursor to different favoring agents like, vanillin and roasted coffee. I It is used as an antiseptic, analgesic and sedative drug for the treatment of dental pulp and periodontal tissue. Glutathione Peroxidase 1 (PDB: 1GP1 ​) Peroxidases or peroxide reductases (EC number 1.11.1.x) are a large group of enzymes which play a role in various biological processes. They are named after the fact that they commonly break up peroxides. Activity of peroxidase in presence of guaiacol and H 2 O 2 was optimum after incubation at 40 °C. Maximum activity of peroxidase is 300%.Activity increased to 240%, 300%, 70% and 10% after 60 minute incubation at 30, 40, 45 and 60 °C for peroxidase.

40 healthy women ages 23-38 who did not take any oral contraceptive and who were not using an IUD comprised the comparison group, 24 women who had IUD inserted for 1-6 months and 18 women with Peroxidase activity was discovered by Schonbein in 1855 when treating guaiacol with hydrogen peroxide and plant extracts. Peroxidases are found in all plants and animals, and are essential for living systems. 1 They catalyze the abstraction of one or two electrons (usually two) via a single-electron transfer from an organic substrate, hydrogen peroxide being used as electron acceptor according to Equation (1) : Peroxidase (Donor: H2O2 Oxidoreductase E.C. Peroxidase (POD) includes in its widest sense a group of specific enzymes such as NAD-Peroxidase, NADP-Peroxidase, fatty acid peroxidase etc. as well as a group of very non-specific enzymes from different sources which are simply known as POD (donor: H 2 O 2-oxidoreductase catalyses the dehydrogenation of a large number of Pre-steady-state kinetic analyses demonstrated that guaiacol is a good substrate for both compounds I and II, the two- and one-electron oxidized enzyme intermediates, respectively, of lignin peroxidase.
