Soy bean phospholipid Chemical Properties,Usage,Production

Chemical Properties

Phospholipids are a kind of main compound fat existing in nature, which widely exists in the brain, nervous system, heart, liver and other organs of human and animal bodies, and various microorganisms, eggs and most of the plant seeds, and almost all the biological cells contain phospholipids. Industrial grade soy lecithin has three categories according to color: natural, bleached and twice bleached, which are brown to light yellow. The purified lecithin is nearly white, after placing, it gradually turns yellow to brown, without odor. mp160℃. Soluble in vegetable oil and ether, soluble in ethanol, insoluble in acetone. Hygroscopicity is very strong. With cadmium salts, etc. can produce insoluble complexes. At any pH value, it exists in amphoteric ionic state, so it has surface-active effect. Phosphatidylcholine is the main active ingredient in soy phospholipids for the treatment of hyperlipidemia. The mechanism may be related to the fact that phosphatidylcholine is absorbed into the bloodstream by the intestinal tract and is mainly incorporated into HDL-C, which provides a substrate for the conversion of cholesterol into cholesteryl esters and activates lecithin cholesterol acyltransferase, promoting the stabilization of apolipoprotein AI. The effective dose of soy lecithin in the treatment of hyperlipidemia is at least 10g per day for 2 months for adults to have a significant effect. Soy phospholipids have a significant therapeutic effect on acute cerebral infarction, the mechanism may be to reduce the decline in phospholipid content in the brain during cerebral infarction. The acid value and iodine value of soybean phospholipids changed the least and the properties were stable when in pill dosage form, aluminum foil packaging, 4℃, and containing less than 2% water. Succinate cytochrome C reductase (SCR) is a tight complex of complex II (SQR) and complex III (QCR), SQR is mainly the hydrophilic part, while QCR is mainly the hydrophobic part.The main components of phospholipids in SCR are PC, PE and CL.The roles of phospholipids in SCR were investigated by Li Lu et al. The effect of phospholipids on the recombination viability of SCR was mainly manifested in the effect on QCR. The recombination viability of either simple phospholipid was inferior to that of soybean phospholipids, but the recombination activity of single phospholipid mixtures with appropriate ratios was much higher than that of soybean phospholipids. The optimal phospholipid ratio for viability recovery contained about 60% PE and CL, with about 40% CL. The reason why the reconstitution activity of soybean phospholipids does not reach the maximum value is related to the fact that the proportion of its CL content is too small. Phospholipids are mostly separated by thin-layer chromatography and high-performance liquid chromatography. Xingquan Li et al. separated phosphatidylcholine (PC) and phosphatidylethanolamine (PE) by silica gel column chromatography using thin-layer chromatography as a precursor. The method is as follows: extraction of total phospholipids. About 1 g of brain tissue (pig brain, mouse brain) was taken, rinsed with saline, 3 ml of mixed solvent was added at the ratio of chloroform: methanol = 1:2 (v/v), homogenized in an ice bath, then 8 ml of mixed solvent was added at the ratio of chloroform: methanol = 2:1 (v/v), stirred, centrifuged for 10 min, and then the first portion of the supernatant was carefully dispensed with a long dropper. To the remaining precipitate add 5 ml of mixed solvent in the ratio of chloroform: methanol=4:1 (v/v), treat as above and divide out the second portion of supernatant. The two (I+II) supernatants were combined and 1 drop of 15 mol/L NH3-H2O was added and blown dry with nitrogen to obtain a milky white liquid. Thin-layer separation of total phospholipids. The chromatographic conditions were as follows: thin-layer plate-silica gel G plate; unfolding agent-chloroform: methanol: ammonia=13.5:6.5:1.0 (v/v); and iodine vapor as the color developer.The TLC results showed that the total phospholipids contained PC and PE components, and the two were well separated. Column chromatography of total phospholipids. Conditions: adsorbent, 200-300 mesh silica gel for chromatography, dry packed column; eluent, chloroform: methanol: ammonia = 13.5:6.5:1.0 (v/v); sample, the extracted total phospholipids with chloroform dissolved as 1.5 ml. Methods: the samples were loaded onto the column at one time, eluted with the above eluents, and collected by divisions, each of which was 1 ml, and a total of 16 copies were collected. After TLC examination, the same parts were combined, of which the 4th and 5th parts were PE parts and the 9th and 10th parts were PC parts.

Uses

Soy bean phospholipid is a source of choline and essential fatty acids and is widely used as a bioactive food additive. In addition, it is used as a wetting agent, solubiliser, emulsifier, liposome builder and technical aid in pharmaceutical, cosmetic or health nutritional products.

Preparation

Concentrated soybean phospholipids are products obtained by drying and dehydrating hydrated soybean crude oil foot. Industrial methods preparing concentrated soybean phospholipids include continuous and batch processings.

Biochem/physiol Actions

The mechanism of activity of Soy bean phospholipid is mainly based on their similarity to phospholipids found in biological membranes and blood lipoproteins. This similarity permits the incorporation of plant phospholipids into these structures and promotes the prevention of a number of pathological processes. Soya phospholipids have a wide range of biochemical and physical effects. Lecithin complexes are readily available sources of linoleic acid, choline and inositol. Lecithin also plays a significant role as an antioxidant booster. The health benefits of taking soy lecithin have been demonstrated and include lowering blood lipids, controlling blood cholesterol and triglyceride levels, stabilising membrane function, and supporting liver function.
