| Introduction | High-purity arachidonic acid is the synthesis of prostaglandin (prostaglandins), thromboxane (thromboxanes) and leukotriene (leukotrienes) The direct precursor of carbon derivatives, these biologically active substances play a very important role in the human cardiovascular system and immune system. |
| Unsaturated fatty acid | Arachidonic acid, referred to as ARA. It is an omega-6 polyunsaturated fatty acid that is commonly found in our foods, such as beef, chicken, eggs, or fish. Generally speaking, we can consume 100-200 mg of arachidonic acid per day. Arachidonic acid is one of the most active omega-6 fatty acids. It plays an important role in the development of the nervous system, the maintenance of immunity, the development of memory/learning ability, the maintenance of bone mineral density, the health of pancreatic islets, and the health of the heart and blood system. Arachidonic acid is common in land animal fats such as pig fat and tallow, but the content is not high, generally less than 1%; it is rare in vegetable oils, only found in moss and fern seed oil There are trace amounts; it mainly exists in marine fish oil. Studies have found that the content of arachidonic acid in adrenal phospholipid fatty acids in land animals (pigs, cattle) is as high as more than 15%. Industry mainly uses microbial fermentation to produce AA, which is an important precursor for human body to synthesize prostaglandins. |

| efficacy and action | 1. regulation of cardiac excitability latest research reports that arachidonic acid and its metabolites such as LTC4 can activate the toxicosine-like K channel coupled to the heart and G protein in a receptor-independent manner, and regulate cardiac excitability under physiological and pathological conditions. 2. involved in neuroendocrine arachidonic acid can stimulate the secretion of anterior pituitary, placenta and mast cells, and participate in regulating the secretion of various hormones and neuropeptides in various neuroendocrine tissues, such as oxytocin, vasopressin, insulin and glucagon. 3. promoting cell division arachidonic acid and its metabolites can promote cell division, and its metabolites have this effect in smooth muscle cells, fibroblasts and lymphocytes. 4. inhibition of platelet aggregation arachidonic acid and its metabolites can cause vasodilation. Vascular endothelial cells are closely related to arachidonic acid enzyme, which can release vasodilator, relax vascular smooth muscle and relax blood vessels under certain stimulation. due to the above physiological functions, arachidonic acid is widely used in cosmetics, medicine, food and other fields. |
| use | nutritional additives. Valium, anti-peptic ulcer and gastrointestinal dysfunction, acts on the uterus. Arachidonic acid is an important substance in the development of human brain and optic nerve, and plays an important role in improving intelligence and enhancing visual acuity. Arachidonic acid has a series of physiological activities such as esterifying cholesterol, increasing vascular elasticity, reducing blood viscosity, and regulating blood cell function. Arachidonic acid has important effects on the prevention of cardiovascular diseases, diabetes and tumors. Raw materials for the synthesis of prostaglandins. Regulates the permeability of human cell membranes. It is very important for the brain and nerve development of infants and young children, and the development of the optic nervous system. It also plays an important role in the treatment of coronary heart disease, diabetes and the prevention of cerebrovascular diseases. Nutritional fortifier. |
