7 Benefits of Linoleic Acid CAS NO 60-33-3 for the Human Body


What Is Linoleic Acid?

Linoleic acid is an essential omega-6 fatty acid, meaning that the human body cannot produce it on its own and must obtain it from dietary sources. It is a polyunsaturated fatty acid with 18 carbon atoms and two double bonds, making it chemically known as cis-9, cis-12-octadecadienoic acid.

Linoleic acid plays several crucial roles in the body, including serving as a precursor for the synthesis of other important compounds, such as arachidonic acid, which is further metabolized into various signaling molecules involved in inflammation and immune responses. Additionally, linoleic acid is a component of cell membranes and is involved in maintaining their structure and function.

Good dietary sources of linoleic acid include vegetable oils (such as soybean, sunflower, safflower, and corn oil), nuts, seeds, and certain types of meat.


Linoleic acid, an essential omega-6 fatty acid, plays several crucial roles in the human body. Its benefits include:

1. Cell Structure and Function

- Membrane Integrity: Linoleic acid is a key component of cell membranes, contributing to their fluidity and flexibility.

- Barrier Function: It helps maintain the barrier function of the skin, preventing excessive water loss and protecting against pathogens.

2. Inflammatory Response

- Linoleic acid is a precursor to arachidonic acid, which is involved in the synthesis of eicosanoids. These signaling molecules play roles in regulating inflammation, immune responses, and blood pressure.

3. Skin Health

- Moisturization: Essential for maintaining skin hydration and integrity, preventing dryness and scaling.

- Anti-inflammatory: Can help reduce inflammation in certain skin conditions like eczema and psoriasis.

4. Heart Health

- Cholesterol Regulation: Some studies suggest that linoleic acid can help lower LDL (bad) cholesterol levels, potentially reducing the risk of heart disease.

5. Brain Function and Development

- Linoleic acid is important for brain development and function. It is involved in the growth and maintenance of neural tissues.

6. Reproductive Health

- It plays a role in reproductive health, particularly in the formation and function of reproductive tissues.

7. Nutritional Support

- As an essential fatty acid, linoleic acid must be obtained through diet. Common sources include vegetable oils (such as sunflower, safflower, and corn oil), nuts, and seeds.
