Soy lecithin. Properties

Soy Lecithin is a complex mixture of phospholipids, which are the majority lipid of cell membranes. The most abundant phospholipid is phosphatidylcholine mixture, known as lecithin. Also in soy lecithin is choline, inositol phospholipids, ethanolamine phospholipids, phosphorus, potassium, inositol and soybean oil.

Phosphatidylcholine plays an important role in fat metabolism, it is part of the enzyme LCAT (Lecithin-Cholesterol Acyl Transferase). This enzyme catalyzes the esterification of HDL cholesterol. This reaction is essential for the uptake of cholesterol from cells and of LDL by HDL for transport to the liver, "sweeping" and the movement of cholesterol from tissues.

Soy Lecithin also contains choline. Choline is an aminoalcohol from which the body is able to synthesize phospholipids and acetylcholine. Acetylcholine is a neurotransmitter involved in learning and memory processes.

Inositol phospholipids and ethanolamine are common phospholipids in cell membranes.

Body functions:

The elevated plasma cholesterol levels are associated with cardiovascular disease. Both the concentration of cholesterol in the blood and platelet adhesiveness with factors involved in atherosclerosis.

We have studied the potential effect of lecithin hipocolesteromiante, found mixed results, although we accept the idea that soy lecithin is its ability hipocolesteromiante their content of linoleic acid (8) (9).

While no soy lecithin produces significant changes in the overall rate of cholesterol and its esterification, they have been observed decreases in serum triglycerides and phospholipids.

In individuals with elevated triglyceride levels was observed an increase in HDL-cholesterol and decreased triglycerides (11).

Recent studies conducted by researchers at the University of Montreal have shown that soy lecithin in the diet increases the secretion of biliary lipids from HDL and cholesterol deposits and fosfatilcolina of liver microsomes. So Soya Lecithin increases the secretion of bile and helps prevent cholestasis (bile duct obstruction). Hill contributes to this effect, postulated to be due to modulation and increased HDL cholesterol and phospholipids for biliary secretion (12).

An additional effect of Soya Lecithin is an increase in arachidonic acid in phospholipids of polymorphonuclear leukocytes, increase phagocytosis and killing capacity of these cells of our immune system (13).

Since Soya Lecithin contains choline, which is involved in the synthesis of neurotransmitters, their inclusion in the diet has beneficial effects on the hill nervioso.También system is responsible for urinary excretion of carnitine is reduced when taking Lecithin Soy. Carnitine is a molecule of the cell membrane that allows passage of fatty acids inside the cells for oxidation and energy production. Soy Lecithin helps to maintain this molecule in muscle cells and increases its synthesis. This translates into an increase in physical performance. In addition, intense exercise causes a drop in plasma choline that can be prevented by choline supplementation before exercise (14).


Lecithin is a dietary supplement that helps reduce cholesterol levels. Phosphorus contributes, so that helps strengthen the brain against memory failures and in cases of lack of concentration.

It is indicated in slimming diets and fat burning in adipose tissue.

The genistein (soy) is a plant hormone that can help women in menopause to replace the estrogen deficiency and the unwanted effects of hot flashes, restlessness, nervousness that they are associated.
