enzymatic  [ˌɛnzaɪˈmætɪk -zɪ-], enzymic [ɛnˈzaɪmɪk -ˈzɪm-] adj

enzyme  (nzm)
Any of numerous proteins produced in living cells that accelerate or catalyze the metabolic processes of an organism. Enzymes are usually very selective in the molecules that they act upon, called substrates, often reacting with only a single substrate. The substrate binds to the enzyme at a location called the active site just before the reaction catalyzed by the enzyme takes place. Enzymes can speed up chemical reactions by up to a millionfold, but only function within a narrow temperature and pH range, outside of which they can lose their structure and become denatured. Enzymes are involved in such processes as the breaking down of the large protein, starch, and fat molecules in food into smaller molecules during digestion, the joining together of nucleotides into strands of DNA, and the addition of a phosphate group to ADP to form ATP. The names of enzymes usually end in the suffix -ase.

Because the spectrum of constitutive and inducible enzymes in the skin is unknown, further metabolism and toxicokinetic studies are warranted to investigate naphthalene metabolism involving various mixed-function oxygenases and conjugation enzymes and their relative spectrums.
There are 2 COX isoforms; COX-1 is a constitutive enzyme expressed in many tissues, including the human intestine and colon, whereas COX-2 is an inducible enzyme expressed in macrophages, epithelial cells, fibroblasts, and other cell types in inflammation.
The higher inducible enzyme activity was also observed in individuals with a 96 bp insertion ([Ins.
