The main difference between linoleic acid and conjugated linoleic acid is that the linoleic acid is a type of polyunsaturated omega-6 fatty acid with an 18-carbon chain with two double bonds in the cis configuration whereas the conjugated linoleic acid can be either in cis or trans configuration and the double bonds are conjugated and separated by a single bond.
Linoleic acid and conjugated linoleic acid are two forms of fatty acids required by the body for the various health benefits. Furthermore, linoleic acid is one of the two essential fatty acids while conjugated fatty acid is a dietary supplement for weight loss.

Arachidonic Acid (AA), Conjugated Double Bonds, Conjugated Linoleic Acid (CLA), Linoleic Acid (LA), Omega-6 Fatty Acids
What is Linoleic Acid
Linoleic acid (LA) is a polyunsaturated, omega-6 fatty acid with a hydrocarbon chain of 18 carbon atoms. Here, this hydrocarbon chain has two C-C double bonds and two single bonds separate them. In nature, linoleic acid occurs as triglyceride esters. Also, a few linoleic acids occur in food as free fatty acids. Some sources of linoleic acids are nuts and fatty seeds like poppy, sesame, hemp, and flax seeds.
Besides, linoleic acid is one of the two essential fatty acids of the body. The second one is the alpha-linoleic acid, which is a form of omega-3 fatty acids. Because of that, the body cannot synthesize linoleic acid. Hence, we have to include them in the diet. Moreover, linoleic acid is also a requirement for the biosynthesis of arachidonic acid, which has connections to various other biochemical pathways. Linoleic acid also occurs in the cell membrane lipids.
What is Conjugated Linoleic Acid
Conjugated linoleic acid (CLA) is an isoform of linoleic acid, mainly found in the meat and dairy products of ruminants. As same as in linoleic acid, it also contains two double bonds, . But, they are conjugated double bonds since these bonds are separated by only one single bond. Moreover, it can occur in both cis and trans configurations. The cis form consists of a lower melting point.
Besides, the conjugated linoleic acid plays an important role as a dietary supplement due to its various health benefits. The main health benefit of the conjugated linoleic acid is its role in weight loss. A combination of conjugated linoleic acid and aerobic exercises can improve muscle power, muscle endurance, breathing, and fatigue. Apart from that, conjugated linoleic acid is effective for high blood pressure, obesity, diabetes, high cholesterol, asthma, breast cancer, and, allergies.
Similarities Between Linoleic Acid and Conjugated Linoleic Acid
- Linoleic Acid and conjugated linoleic acid are two types of fatty acids the body requires.
- They are carboxylic acids having a hydrocarbon chain with 18 carbon atoms.
- Also, both are polyunsaturated fatty acids, which contain two double bonds in the hydrocarbon chain.
Difference Between Linoleic Acid and Conjugated Linoleic Acid
Linoleic acid refers to a polyunsaturated fatty acid present as a triglyceride in linseed oil and other oils and essential in the human diet while conjugated linoleic acid refers to any of the several isomers of linoleic acid characterized by conjugated double bonds and are found in various foods. Hence, this is the basic difference between linoleic acid and conjugated linoleic acid.
A main difference between linoleic acid and conjugated linoleic acid is their double bonds. The double bonds of linoleic acid are not conjugated while the double bonds of the conjugated linoleic acid are conjugated.
Another major difference between linoleic acid and conjugated linoleic acid is that the linoleic acid occurs in cis configuration while the conjugated linoleic acid occurs in both cis and trans configurations.
Linoleic acid is one of the two essential fatty acids required by the body while conjugated linoleic acid is used as a dietary supplement for weight loss. Thus, this is another important difference between linoleic acid and conjugated linoleic acid.
Also, linoleic acid occurs in nuts and fatty seeds while conjugated linoleic acid occurs in meat and dairy products of ruminants.
Linoleic acid is a polyunsaturated, omega-6 fatty acid and it is one of the two essential fatty acids in the body. It is required by the biosynthesis of arachidonic acid, which is connected with various other biochemical pathways. On the other hand, conjugated linoleic acid is an isoform of linoleic acid and its double bonds are separated by one single bond. It is important for bodybuilding purposes. Thus, the main difference between linoleic acid and conjugated linoleic acid is their structure and importance.
