The role of linoleic acid and linolenic acid?

1. Linoleic acid has the functions of lowering blood lipid, softening blood vessels, lowering blood pressure and promoting microcirculation, and can prevent or reduce the incidence of cardiovascular diseases, especially for the prevention and treatment of hypertension, hyperlipidemia, angina pectoris, coronary heart disease, atherosclerosis, senile obesity, etc. It can prevent the deposition of human serum cholesterol on the blood vessel wall, and has the reputation of "blood vessel scavenger", and has the prevention and treatment of atherosclerosis and cardiovascular diseases.

2. α -linolenic acid is beneficial to brain health and intelligence improvement. α -linolenic acid is an essential factor to maintain the function of brain and nerve. It is worth noting that about 6% of human brain is composed of fat, nerve growth needs α -linolenic acid as raw material, and nerve and neuron need α -linolenic acid to provide energy.

DHA, a derivative of α -linolenic acid, is an important substance in the brain. It can promote the synthesis of protein and monoamine neurotransmitters in the brain, and plays an important role in the formation, growth, proliferation, differentiation and maturation of brain neurons, glial cells and nerve conduction synapses.

it can improve the permeability of the cerebral nerve membrane and the presynaptic membrane, make the nerve information transmission pathway unblocked, improve the nerve reflex ability, and then enhance people's thinking ability, memory ability and stress ability.

Extended information:

Linoleic acid is a fatty acid that cannot be synthesized by human body, or the synthetic amount is far from meeting the needs, which is called essential fatty acid. Linoleic acid is recognized as an essential fatty acid. Linoleic acid has attracted much attention because it can reduce blood cholesterol and prevent atherosclerosis.

It is found that cholesterol must be combined with linoleic acid before it can function and metabolize normally in the body. If linoleic acid is lacking, cholesterol will combine with some saturated fatty acids, cause metabolic disorder, deposit on the blood vessel wall, gradually form atherosclerosis, and cause cardiovascular and cerebrovascular diseases.

genetic relationship

α -linolenic acid is more effective than DHA, etc. α -linolenic acid can be transformed into DHA, DPA, EPA, etc. in vivo, and DHA supplementation can only play a part. α -linolenic acid is the mother of DHA.

Shortboard of Nutrition

If eight kinds of nutrients are compared to wooden boards, they * * * together form a wooden barrel, then α -linolenic acid will be the shortest board for everyone, and its height directly determines the level of health and nutrition.
