Currently, lecithin used as food, nutritional supplements and other purposes are generally derived from egg yolk and soybeans. Soybean lecithin contain a large amount of essential fatty acids with high physiological activity (linoleic acid and linolenic acid content are more than 60%) because they do not contain cholesterol, and in terms of industrial production, their production costs are much lower than egg yolk lecithin. Therefore, as a natural active ingredient and pharmaceutical conditioner, it is widely used in the pharmaceutical industry.
When soybean lecithin are used as medicines, their physiological functions can be roughly summarized as follows:
1. Relieve arteriosclerosis: improve the composition of the arterial vessel wall, maintain the activity of cholesterol esterase; increase the content of high-density cholesterol lipoprotein; prevent heart machine infarction, cardiac membrane stenosis and cerebrovascular disorders.
2. Improve lipid metabolism in the body: improve serum lipids to reduce serum total cholesterol and neutral fat content; prevent blood clotting; lower blood pressure and remove cholesterol gallstones.
3. Promote the absorption of fat and fat-soluble vitamins in the body.
4. Eliminate liver lipid metabolism disorders: prevent hepatitis and fatty liver.
5. Regulate nerve function: Enhance memory, prevent and treat senile diseases such as abnormal muscle and nerve function.
