Metabolite Identification
Common Name16(R)-HETE
Description16(R)-HETE is a metabolite of arachidonic acid, metabolized by the enzyme Cytochrome P450, family 2, subfamily C [EC:1.14.13.80 1.14.13.48 1.14.13.49]. 16(R)-HETE is an endogenous lipidic inhibitor of human neutrophil inhibitor of adhesion and aggregation activity. Human polymorphonuclear leukocytes (PMNs) produce 16(R)-HETE that modulates their function. HETEs have different biological properties based on sites of production and can be stored in tissue lipids and released in response to hormonal stimuli. Eicosanoids generated during the actions of growth factors and vasoconstrictors can modulate disease processes by affecting vascular homeostasis, inflammation, cellular growth, apoptosis and oxidant stress. In lung, the presence of these eicosanoids in the pulmonary vasculature and airways, including effects on pulmonary vascular and bronchial smooth muscle tone and airway epithelial ion transport.
