I believe a simple change in DNA results in Mutation. A mutation is a random spontaneous changes that occur in the genetic make up of an organism ( in the DNA sequences). The mutation are either due to mistakes when DNA are being copied or as a result of environmental factors such as UV light and cigarette smokes among other mutagens. Mutations may be either gene mutation (permanent alteration in the DNA sequence that makes up a gene) or chromosomal mutation.
The enzyme is lipoxygenase.
Lipoxygenase is a variety of enzymes that can cause oxidation of fatty acids. There are several varieties of lipoxygenases, some of which are present in plants. They are involved in the formation of white blood cells that are involved in some severe allergic reactions (anaphylaxis). <em>It is based on this knowledge that antiallergic drugs have been developed to inhibit the activity of lipoxygenase, including reducing inflammatory reactions.</em>
Leukotrien are named thus because they were discovered in leucocytes and that they are unsaturated lipids with 3 conjugated double bonds (trienes) and 20 carbon atoms
