| Physical and Chemical Properties | Lecithin has broad and narrow sense, narrow sense of lecithin refers to phosphatidylcholine, broadly refers to PC, PE, PI (phosphatidylinositol, phosphatidyl inositol), PS (serine phospholipids, phosphatidyl serines), including phospholipids. Phosphatidylcholine in the brain, nerve tissue, liver, adrenal gland and red blood cell content is more, the content of egg yolk (about 8%-10%), so called lecithin. Lecithin has two kinds of isomers, α and β, depending on the position where phosphoric acid is attached to glycerol. Lecithin in nature is α-type. Almost saturated fatty acids are attached at the carbon position, while unsaturated fatty acids such as oleic acid, linoleic acid, linolenic acid and arachidonic acid are usually attached at the β position. The nitrogen-containing organic base in lecithin in combination with phosphoric acid is choline. In the lecithin molecule, the β carbon atom of the glycerol moiety is a chiral carbon atom, and thus there are both D-type and L-type configurations. Naturally occurring is the L-type. This product is composed of several parts of phospholipid molecules, unsaturated fatty acids, choline and inositol. Pure lecithin is a water-absorbing white wax that changes to a yellow or brown translucent waxy mass in the air due to oxidation of unsaturated fatty acids. The acetone precipitation of lecithin in granular or powder. Soluble in petroleum ether, chloroform, ether, benzene and ethanol, insoluble in acetone, insoluble in water. It is hygroscopic, easy to oxidize, and gradually darkened in air. Lecithin is hydrolyzed in the human body to glycerol, unsaturated fatty acids, choline and phosphoric acid, in which the phosphate group is hydrophilic and the fatty acid group is lipophilic. These two groups make lecithin emulsifiable. The physiological role of lecithin: the main component of the cell membrane, can promote the cell to absorb nutrients to eliminate toxic waste. It can assist the absorption of fat-soluble vitamins A, D, E and K and increase the utilization rate of these vitamins by 100%. Supplementing enough lecithin can enhance the vitality of cells, enhance the immunity and disease resistance of human body. Powerful emulsifier, it can make the blood cholesterol and neutral fat into very small particles, in order to facilitate the absorption and metabolism of tissues, thereby preventing the deposition of cholesterol in blood vessels, prevent cholesterol deposition caused by atherosclerosis, high blood pressure and heart disease. More typically compatible molecules, involved in the composition of various lipoproteins. It is an indispensable substance for the catalysis of various lipid-dependent enzymes. It is related to the mechanism of action of hormones. It plays an important role in the transmission of nerve excitation. Sun runguang et al. studied lecithin-porphyrin metal complexes (Now called complex coordination compounds, referred to as complexes) conductivity. The results show that: when the general electrode and lecithin-porphyrin metal complexes (such as Ni porphyrin, Mg porphyrin) electrode composed of the primary battery, the electromotive force is 1-2 times of the general electrode composed of the electromotive force of the primary battery. Small angle X-ray scattering (SAXS) method was used to study the structural changes of lecithin-porphyrin metal complexes, when the electrodes are made of chloroform and secondary distilled water in different proportions, the molecules of the porphyrin metal complexes interact with the lecithin molecules, so that the porphyrin metal complexes are embedded between the lecithin molecules, A substance in the liquid crystal state is formed. These liquid crystalline substances are coated on the surface of the electrode to form a liquid crystalline film layer, which has a high order. Due to the existence of the liquid crystal film, the potential of the original conductive glass and the conductive liquid is changed, which is beneficial to the electron transfer of the porphyrin metal complex, and the conductivity of the lecithin-porphyrin metal complex electrode is increased, thus, the electrode potential is changed, and the electromotive force is significantly improved compared with the electromotive force generated by the conductive glass electrode which is not coated with such a liquid crystal substance. |
