Food products from ruminants are the major dietary source of conjugated linoleic acids (CLA) for humans. The uniqueness of CLA in ruminant fat relates to the biohydrogenation of dietary unsaturated fatty acids by rumen bacteria. The CLA are intermediates in the biohydrogenation, and a portion escape the rumen and are incorporated into milk fat and body fat. In addition, the animal itself synthe...

The object of this review is to create an overview of Conjugated Linoleic Acid (CLA), from the presence of these molecules in products of animal origin to the benefits brought to the health of human beings who ingest these products. We will examine the literature to describe the CLA synthesis process in the rumen and in tissues and the method by which CLA becomes incorporated into consumer prod...

Linoleic acid is the fatty acid under which the omega-6 fatty acids, a type of ?good fat [2]?, are categorized. Conjugated linoleic acid (CLA), on the other hand, has the same molecular formula as linoleic acid but a different chemical structure. These essential nutrients aren?t produced by the human body and therefore must be ingested from plantand animal-based food products, such as vegetable...

Introduction Conjugated linoleic acid (CLA), a naturally occurring trans fat, is commonly found in ruminant animal sources such as beef, lamb, and dairy products (e.g., milk and cheese). Over the past two decades a wealth of research, mainly from in vitro and experimental animal studies and limited human investigations, has examined potential health benefits of CLA. This research on the biologi...

Fatty acids containing trans unsaturated double bonds occur in nature, but the most common dietary source are “man-treated” fats. Because of the possible link between trans-fatty acids consumption and human disease-mainly cardiovascular disease and cancer, the health effects of trans-FA have been studied for over the last fifty years. Trans fatty acids are unsaturated fatty acids with at least ...

The oxidation rates for conjugated linoleic acid (CLA), linoleic acid (LA), and their methyl and ethyl esters were measured in aqueous and solvent systems by the induction period method. In an aqueous system, the initiation rate was almost the same for all the samples, except for ethyl conjugated linoleate (ECL). The propagation rate, oxidizability, and kinetic chain length were different for t...

A survey of 30 representative strains of human gram-positive intestinal bacteria indicated that Roseburia species were among the most active in metabolizing linoleic acid (cis-9,cis-12-18:2). Different Roseburia spp. formed either vaccenic acid (trans-11-18:1) or a 10-hydroxy-18:1; these compounds are precursors of the health-promoting conjugated linoleic acid cis-9,trans-11-18:2 in human tissu...
