Phospholipids

Phospholipids Uses, Dosage, Side Effects, Food Interaction and all others data.

Phospholipids are polyunsaturated fatty acids (PUFAs) with a double bond at the third carbon atom from the end of the carbon chain. The three types of omega-3 fatty acids involved in human physiology are α-linolenic acid (ALA) (found in plant oils), eicosapentaenoic acid (EPA), and docosahexaenoic acid (DHA) (both commonly found in fish oil that originally come from microalgae that is further consumed by phytoplankton, a source of diet for fish). Phospholipids play a critical role in metabolism and cellular function and they are available as daily supplements. On September 8, 2004, the U.S. Food and Drug Administration gave "qualified health claim" status to EPA and DHA omega-3 fatty acids. Therapeutic products containing omega-3 fatty acid and its derivatives for treatment of hypertriglyceridemia include Lovaza, Omtryg, Epanova, and Vascepa.

Phospholipids are triglycerides that get broken down into smaller fatty acid units. They act to reduce plasma triglyceride levels however increase the cholesterol levels and are thought to possess potent antiarrythmic effects. Polyunsaturated fatty acids including eicosapentaenoic and docosahexaenoic acid mediate important cellular function such as inhibition of platelet function, prolongation of bleeding time, anti-inflammatory effects and reduction of plasma fibrinogen. Polyunsaturated fatty acids are components of the phospholipids that form the structures of the cell membranes and also serve as energy source. They form eicosanoids which are important signalling molecules with wide-ranging functions in the body's cardiovascular, pulmonary, immune and endocrine systems. DHA tends to exist in high concentrations in the retina, brain (via uptake by Mfsd2a as a transporter), and sperm.

Uses

Phospholipids is an ingredient found in a variety of supplements and vitamins.

Provided as daily supplements. Aa preparation of omega-3-acid ethyl esters is licensed in UK for prevention of recurrent events after myocardial infarction in addition to treatment of hypertriglyceridaemia.

Phospholipids is also used to associated treatment for these conditions: Nutritional supplementation, Parenteral Nutrition

How Phospholipids works

Phospholipids mediate anti-inflammatory effects and increased levels of EPA or DHA has shown to decrease the levels of PGE2 and 4 series-LT. Eicosapentaenoic acids compete with constitutive levels of arachidonic acid in cell membranes for the same desaturation enzymes and produce 3-series prostaglandins and thromboxanes, and 5-series leukotrienes which have low pro-inflammatory potential. The alteration in leukotriene biosynthesis due to higher concentration of omega-3 fatty acids compared to arachidonic acid underlies the anti-inflammatory effects. EPA and DHA also give rise to resolvins and related lipid signalling molecules such as protectins via cyclooxygenase and lipoxygenase pathways, which have anti-inflammatory effects. They inhibit transendothelial migration of neutrophils and inhibit TNF and IL-1β production. Phospholipids also decrease adhesion molecule expression on leukocytes and on endothelial cells and decrease intercellular adhesive interactions. Omega-3 (or n-3) polyunsaturated fatty acids (PUFAs) and their metabolites are natural ligands for peroxisome proliferator-activated receptor (PPAR) gamma that regulates inflammatory gene expression and NFκB activation. PPAR alpha activation is also associated with induction of COX-2 expression. The role of EPA and DHA in reducing triglyceride levels include inhibition of acyl-CoA:1,2-diacylglycerol acyltransferase, increased mitochondrial and peroxisomal-beta-oxidation in the liver, decreased lipogenesis in the liver, and increased plasma lipoprotein lipase activity. They also may reduce triglyceride synthesis because they are poor substrates for the enzymes responsible for TG synthesis, and EPA and DHA inhibit esterification of other fatty acids.

Elimination Route

After ingestion, dietary lipids are hydrolyzed in the intestinal lumen. The hydrolysis products—monoglycerides and free fatty acids—are then incorporated into bile-salt– containing micelles and absorbed into enterocytes, largely by passive diffusion. The absorption rate is about 95%. Within intestinal cells, free fatty acids are primarily incorporated into chylomicrons and enter the circulation via the lymphatic system where they are delivered to various tissues for metabolism, oxidation and storage.
