Trans fat, also called trans-unsaturated fatty acids, or trans fatty acids, is a type of unsaturated fat that occurs in foods. Small amounts of trans fats occur naturally, but large amounts are found in some processed foods. Since consumption of trans fats is unhealthy, [a] artificial trans fats are highly regulated or banned in many nations.
Trans fat regulation, that aims to limit the amount of "trans fat" — fat containing trans fatty acids — in industrial food products, has been enacted in many countries. These regulations were motivated by numerous studies that pointed to significant negative health effects of trans fat. It is generally accepted that trans fat in the diet is ...
Trans fat has been found to act like saturated in raising the blood level of LDL ("bad cholesterol"); but, unlike saturated fat, it also decreases levels of HDL ("good cholesterol"). The net increase in LDL/HDL ratio with trans fat, a widely accepted indicator of risk for coronary artery disease, is approximately double that due to saturated fat.
Elaidic acid. Elaidic acid has 18 carbons and is a trans -9-mono-unsaturated fatty acid. It is also a trans isomer of oleic acid. C 17 H 33 CO 2 H, IUPAC organization name (E)-octadec-9-enoic acid, numerical representation 18:1 (9), n-9, molecular weight 282.46, melting point 43–45 °C. CAS Registry Number 112-79-8.
An unsaturated fat is a fat or fatty acid in which there is at least one double bond within the fatty acid chain. A fatty acid chain is monounsaturated if it contains one double bond, and polyunsaturated if it contains more than one double bond. A saturated fat has no carbon-to-carbon double bonds, so the maximum possible number of hydrogen is ...
Unsaturated ones are typically bent, unless they have a trans configuration. In chemistry, particularly in biochemistry, a fatty acid is a carboxylic acid with an aliphatic chain, which is either saturated or unsaturated. Most naturally occurring fatty acids have an unbranched chain of an even number of carbon atoms, from 4 to 28. [1]
Conjugated linoleic acids (CLA) are a family of isomers of linoleic acid. In principle, 28 isomers are possible. CLA is found mostly in the meat and dairy products derived from ruminants. The two C=C double bonds are conjugated (i.e., separated by a single bond). CLAs are simultaneously both cis-fats and trans-fats, as one of the two C=C bonds ...
Mary G. Enig. Mary Gertrude Enig (née Dracon; July 13, 1931 – September 8, 2014) [1] was a nutritionist and researcher known for her unconventional positions on the role saturated fats play in diet and health. [2] She disputed the medical consensus that diets high in saturated fats contribute to development of heart disease, [3] while she ...
