In this issue, we will discuss CYP2D6—an enzyme that is involved in the metabolism of numer­ ous drugs. Get tested for pseudocholinesterease — an enzyme that helps break down Esters. In order for DNA to reproduce, the base pairs must be split apart. The UGT1A4 gene encodes an enzyme of the glucuronidation pathway, a phase II metabolism process that transforms small lipophilic molecules into water-soluble excretable metabolites. (Accessed May 26, 2013). Br J Clin Pharmacol 2011;71:611-5. The UGT1A4 enzyme mediates the metabolism of important psychotropic medications, including some tricyclic antidepressants, antipsychotics, and mood stabilizers 1–20 . An enzyme is a molecule that speeds up a reaction. Recall that DNA is a long strand with a many repeating base pairs.

You don’t have the enzyme to utilize the meds so you get sick. Also, you might have combination of other enzyme deficiencies like I do. These toxins, called PAHs (polycyclic aromatic hydrocarbons) are known to be some of the most potent carcinogens in tobacco smoke.
