Part Descriptions

LP33077-6   Eicosapentaenoate
Eicosapentaenoate (EPA) is a long chain omega-3 fatty acid that is present throughout the body including in cell membranes. EPA is found in fatty fish including salmon, tuna, mackerel, sardines, shellfish, and herring. EPA can be biosynthesized from alpha-linolenic acid (ALA), but it is much more efficient to increase levels by including EPA-rich sources in one's diet. EPA has anti-inflammatory properties that are vital to fetal development and the process of healthy aging. Its anti-inflammatory effects are due to reduced gene expression of genes involved in inflammatory and atherogenesis-related pathways, thereby lowering the risk of cardiovascular disease. EPA has also been found to increase platelet stability, decrease endothelial activation, and improve vascular permeability. Taking EPA supplements leads to an increased amount of EPA in the plaque of carotid arteries which may decrease inflammation and increase plaque stability. PMID: 22332096 Many other studies have been run that show acorrelation between higher plasma levels of EPA and reduced symptoms of disease, some of which include Alzheimer's disease, depression, rheumatoid arthritis, and Raynaud Syndrome.[] Source: Regenstrief LOINC

LP69948-5   Arachidonate
Arachidonate (AA) is an essential polyunsaturated omega-6 fatty acid that is produced from dietary linoleic acid. AA is located in human fat, liver, brain, and glandular organs and is a mediator of inflammation. The AA within the phospholipids of cell membranes is the surface where the production of a number of biologically active compounds occurs. A few of the compounds produced includes prostaglandins, thromboxanes, and leukotrienes which regulate processes including platelet aggregation, blood clotting, smooth muscle contraction, leukocyte chemotaxis, inflammatory cytokine production, and immune function.[PubChem: 444899] AA is released from the cell membrane when acted upon by phospholipases and then metabolized by cyclooxygenase (COX) producing the prostanoids prostaglandin and thromboxane A2, which can stimulate or mitigate inflammation. PMID: 21508345 One of the benefits of the Omega-3 fatty acids for patients with inflammatory disease is believed to be their selective modification of the metabolism of AA by the omega-3 fatty acids that results in a reduced amount of inflammation.
