Linolenic acid (C18: 3), is a fatty acid belonging to the group of omega 3 fats, and therefore, it is a polyunsaturated fatty acid.

Linolenic acid (omega-3), along with linoleic acid (omega-6), is one of the essential fatty acids that exist, that is, fats that the organism has to obtain from food, since it is not able to synthesize them by itself.

The structure of this fatty acid is formed by a chain of 18 carbon atoms containing 3 double bonds. It is represented as C18: 3.

The chemical molecular formula of linolenic acid (18: 3) is:

H3C-CH2-CH = CH-CH2-CH = CH-CH2-CH = CH- (CH2) 7-COOH

Through linolenic acid the body can synthesize other polyunsaturated fatty acids of longer chains, such as the following:

Types of Omega 3 Fatty Acids:

- Linolenic acid (C18: 3)

- Alpha-linolenic acid (C18: 3)

- Eicosapentaenoic acid or EPA (C20: 5) (PG3, TX3)

- Docosahexaenoic acid or DHA (C22: 6)

Properties of linolenic acid

Linolenic acid, specifically the isomer we find as alpha-linolenic acid, is the precursor of the following fatty acids that have longer chains, EPA and DHA

Linolenic acid isomers found in the following structures, either as gamma-linolenic acid (C18: 3) or as dihomo-γ-linolenic acid (C20: 3), are of the omega 6 family and do not belong to the omega 3 family.

Our body is not able to synthesize alpha-linolenic acid, but there are some plants like algae and some plankton types that can synthesize it by themselves. That is why it is classified within the group of essential fatty acids.

Importance of essential fatty acids

The body needs these omega 3 fatty acids to work properly. Among its main functions are:

- Functioning of the nervous system: of neurons and chemical transmissions

- The proper functioning of the immune system

- The formation of cell membranes

- To manufacture hormones

- Eye health: For the correct formation of the retina

Foods rich in linoleic acid: Food sources of linoleic acid

Linoleic acid is found in foods of plant origin such as flax seeds and especially flax oil, also called flaxseed oil. Other plants rich in this component are walnuts, chia seeds, soybean, canola oil, evening primrose oil, quinoa, pecans, hemp seeds, etc.

These foods do not contain EPA and DHA.

The only foods that contain sufficient amounts of EPA and DHA are foods of animal origin, and more specifically blue fish such as salmon, tuna, mackerel, herring, etc. Cod liver oil supplements contain EPA and DHA.

Linolenic acid is considered to be less effective than EPA and DHA because it needs to be transformed into the body.
