Fish oil is oil derived from the tissues of oily fish. Fish oils contain the omega-3 fatty acids eicosapentaenoic acid (EPA) and docosahexaenoic acid (DHA), precursors of certain eicosanoids that are known to reduce inflammation in the body and improve hypertriglyceridemia. There has been a great deal of controversy in recent years about the ...

Scandinavian Vikingsproduced cod liver oil by laying birch tree branches over a kettle of water, and fresh livers were laid over the branches. The water was brought to a boil and as the steam rose, the oil from the...
Though similar in fatty acid composition to other fish oils, cod liver oil has higher concentrations of vitamins A and D. According to the United States Department of Agriculture, a tablespoon (13.6 grams or 14.8 mL) of cod liver oil contains 4,080 μg of retinol (vitamin A) and 34 μg (1360 IU) of vitamin D. The Dietary Reference Intake of vitamin A...
A tablespoon (13.6 g) of cod liver oil contains 136% of the UL for preformed vitamin A (retinol). Vitamin A accumulates in the liver, and can reach harmful levels sufficient to cause hypervitaminosis A.Pregnant women may want to consider consulting a doctor when taking cod liver oil because of the high amount of retinol. Fatty acid oxidation and en...
In Newfoundland, cod liver oil was sometimes used as the liquid base for traditional red ochrepaint, the coating of choice for use on outbuildings and work buildings associated with the cod fishery. In Tübingen, Germany, drinking a glass of cod liver oil is the punishment for the loser at the traditional Stocherkahnrennen, a punting boat race by Un...
n-6 DPA is an ω-6 fatty acid with the trivial name osbond acid. It is formed by the stepwise elongation and desaturation of arachidonic acid i.e. 5Z,8Z,11Z,14Z-eicosatetraenoic acid (5,8,11,14-20:4n-6) to the 24 carbon PUFA intermediate (i.e. 6,9,12,15,18:24-5n-6) and the retro-conversion of this intermediate to DPAn-6 as follows:
n-3 DPA is an n-3 fatty acid with the trivial name clupanodonic acid. It is an intermediary between eicosapentaenoic acid (EPA, 5,8,11,14,17-20:5n-3) and docosahexaenoic acid(DHA, 22:6 ω-3) in the following stepwise pathway in which DPAn-3 is a precursor to DHA (6,9,12,15,18,21:24:6n-3) and the final product, 4,7,10,13,16,19-22:6n-3, can be retro-converted to DPAn-3: Mammalian cells, including human cells, metabolize DPAn-3 to an array of products that are members of the specialized proresolv...
Docosapentaenoic acid (DPA) is an n-3 fatty acid that is structurally similar to eicosapentaenoic acid(EPA) with the same number of double bonds, but two more carbon chain units. Dietary sources These are the top five sources for DPA according to the USDA Agricultural Research Service: 1. Fish oil, menhaden 0.668g in 1 tbsp. (13.6g) 2. Fish oil, sa...
Clupanodonic acid, an omega-3 fatty acid, along with its metabolite DHA and other long chain omega-3 fatty acids, is under study to determine properties of omega-3 fats in humans, such as in inflammationmechanisms.

α-Tocopheryl acetate is often used in dermatological products such as skin creams. It is not oxidized and can penetrate through the skin to the living cells, where about 5% is converted to free tocopherol. Claims are made for beneficial antioxidant effects. α-Tocopheryl acetate is used as an alternative to tocopherol itself because the phenolic hyd...
Ingredient in vape liquids
On September 5, 2019, the United States Food and Drug Administration (US FDA) announced that 10 out of 18, or 56% of the samples of vape liquids sent in by states, linked to the recent vaping-related lung disease outbreak in the United States, tested positive for vitamin E acetate which had been used as a thickening agent by illicit THC vape cartridge manufacturers. On November 8, 2019, the Centers for Disease Control and Prevention (CDC) identified vitamin E acetate as a very strong culprit...
At room temperature, α-tocopheryl acetate is a fat-soluble liquid. It has 3 chiral centers and thus 8 stereoisomers. It is made by esterifying α-tocopherol with acetic acid. 2R,4R,8R-isomer, also known as RRR-α-tocopheryl acetate, is the most common isomer used for various purposes. This is because α-tocopherol occurs in the nature primarily as RRR...
