trans fatty acid

n. An unsaturated fatty acid produced by the partial hydrogenation of vegetable oils and present in hardened vegetable oils, most margarines, commercial baked foods, and many fried foods. An excess of these fats in the diet is associated with high LDL cholesterol levels, low HDL cholesterol levels, and an increased risk of coronary heart disease.

Thesaurus

Noun

trans fatty acid - a fatty acid that has been produced by hydrogenating an unsaturated fatty acid (and so changing its shape); found in processed foods such as margarine and fried foods and puddings and commercially baked goods and partially hydrogenated vegetable oilsmargarine, marge, oleo, oleomargarine, margarin - a spread made chiefly from vegetable oils and used as a substitute for butterfatty acid - any of a class of aliphatic monocarboxylic acids that form part of a lipid molecule and can be derived from fat by hydrolysis; fatty acids are simple molecules built around a series of carbon atoms linked together in a chain of 12 to 22 carbon atomselaidic acid - a monounsaturated fatty acid that has the same structure as oleic acid except that it is a trans fatty acid; the major trans fatty acid in margarine and fried foods

trans fatty acid

trans fat

An unsaturated fat containing a trans—i.e., the carbon moieties on the two sides of the double bond point in opposite directions—(E)- isomer. Trans fats (TFs) are not found in nature; minimal TFs are present in animal fats. TFs are abundant in margarines, frying fats and shortenings, and are formed when polyunsaturated fat-rich vegetable and marine oils and vegetable shortenings are “hardened” by partial hydrogenation, producing fats with a firmness and consistency desired by both food manufacturers and consumers. The most abundant TF is elaidic acid and its isomers, which are 18-carbon molecules with one double bond.
TFs comprise 6 to 8% of the daily per capita consumption of fat in developed nations; health experts recommend reduction of TFs to trace amounts, as increased dietary TFs result in increased total and LDL-cholesterol, reduced HDL-cholesterol and an increased risk of coronary artery disease.

trans fatty acid

An unsaturated fatty acid–present in minimal amounts in animal fat–prepared by hydrogenation, which ↑ serum cholesterol Cardiovascular disease ↑ TFAs have a relative risk of 1.4 for CAD in ♂ in the upper quintile for intake of TFAs, and 1.4 for breast CA in ♀ in the highest quartile for TFA consumption. See Fatty acids Clinical nutrition TFAs are abundant in margarines, frying fats and shortenings; TFAs comprise 6–8% of ± 120 g/day/person fat consumption in developed nations; the most abundant TFA is elaidic acid; ↓ dietary TFA result in ↓ total cholesterol; the ratio of total cholesterol to HDL-C is lowest after consumption of soybean oil; Cf Cisfatty acid, Fatty acid, Fish, HDL-cholesterol, LDL-cholesterol, Olive oil, Polyunsaturated fatty acid, Tropical oils, Unsaturated fatty acid.
